Ma muli o ka palena ʻia o nā mea PVC i nā manawa he nui, ua hoʻolaha ikaika ʻia ka elasticity thermoplastic.

I nā makahiki 15 i hala iho nei, ua hoʻonui nui ʻia ka hoʻomohala ʻana o nā elastomers thermoplastic flame retardant ma Kina. ʻO nā elastomers thermoplastic flame retardant, ʻoiai ʻo TPE a me TPU, ua hoʻohana nui ʻia i nā laina ʻikepili huahana mea kūʻai aku, nā laina hoʻouka uila hou a me nā laina insulated, a me nā laina voltage kiʻekiʻe i loko o ke kaʻa.

Eia nō naʻe, nui nā pilikia kūʻokoʻa i ka noiʻi ʻana i ka pale ahi o nā elastomers thermoplastic. No ka laʻana, nīnau pinepine nā hoaaloha i nā ʻokoʻa ma waena o TPE a me TPU. Kūkākūkā pōkole kēia ʻatikala i nā ʻano, ka hoʻohālikelike hana a me ka hoʻohana ʻana o nā elastomers thermoplastic TPE a me TPU uea a me nā mea kaula.

01 Ka hoʻohana ʻana o TPE ma ke kahua o ka uea a me ke kaula

ʻO TPE e pili ana i kahi elastomer thermoplastic me SEBS ma ke ʻano he resin matrix. ʻO SEBS kahi copolymer poloka i haku ʻia me ka styrene (S)-ethylene (E)/butene (B)-styrene (S).

Hoʻopiha ʻia nā pilina pālua ma SEBS, ʻo ia hoʻi, ʻo SBS, e ka hydrogenation, no laila he kūpaʻa maikaʻi ko SEBS i ke aniau, kūpaʻa wela, kūpaʻa i ka hoʻololi ʻana o ke kaomi a me nā waiwai mechanical maikaʻi loa.

(1) Loaʻa i nā huahana SEBS ka hana insulation uila maikaʻi loa, ʻaʻohe ʻawahia, kū i ka wā a me ke kūpaʻa ʻelemakule, maʻalahi maikaʻi a me ka ikaika kiʻekiʻe, a he ākea ka laulā o ka mahana. He mau mea maikaʻi loa lākou no ka hana ʻana i nā uhi waho a me nā lipine insulation o nā uea a me nā kaula. Hoʻohana nui ʻia lākou i nā kikowaena akamai kelepona a me nā mīkini home a me nā ʻoihana ʻē aʻe.

I kēia manawa, ua lilo ia i mea maʻamau e pani i ka PVC ma ke kahua o nā uea haʻahaʻa haʻahaʻa (e like me nā kaula headphone, nā kaula charger, nā kaula USB, nā kaula leo/wikiō, nā kaula kamepiula, a pēlā aku).

(2) No ka mea, he mau ʻano hoʻohou wikiwiki a me ke ola lawelawe pōkole nā ​​huahana uila mea kūʻai aku, me ka hiki ʻana mai o ke au o ka hoʻonui ʻana i ka hoʻohana ʻana, loaʻa i nā huahana pili SEBS kahi ākea no ka hoʻomohala ʻana i kēia ʻoihana.

Me ka hoʻonui ʻia ʻana o nā koi i ke kū'ē ʻana i ke ahi uwea a me ka hana palekana o ke kaiapuni ma ka home a ma waho, ke hoʻomau nei ka pae hoʻohana ʻana o ka poʻe i ka hoʻomaikaʻi ʻana, ke ʻano o nā huahana SEBS flame retardant kiʻekiʻe e paniʻO kēia kaula Ke ʻike nui ʻia nei nā substrates e like me PVC a me CPE i ka wā e hiki mai ana, a he ākea nā manaʻolana noi e hiki mai ana. I kēia manawa, nui ka noi mākeke no ka hoʻololi ʻana i ka pale ahi SEBS a me ka hoʻomohala hana kiʻekiʻe.

Mea hana TPE kūikawā: Me ka hoʻopili ʻana a me ka hoʻomohala ʻana i nā ʻenehana hou o nā mea TPE, ʻo ka mea hana TPE kūikawā o kēia manawa e pili ana i ka conductive TPE, antistatic TPE, TPE insulating material, irradiated crosslinked XLTPO, high resilience TPE, high flame retardant TPE, etc.

02 Ka hoʻohana ʻana o TPU ma ke kahua o ka uea a me ke kaula

ʻO ka TPU thermoplastic polyurethane elastomer, he copolymer poloka linear i hana ʻia e ka hopena o ka diisocyanate a me ka macromolecular polyol, chain extender/crosslinker a me kahi liʻiliʻi o nā mea hoʻohui. ʻO kekahi he mea polyurethane nui, a ʻo kekahi he ʻano polyether nui.

He polymer poloka ia, a ʻo ka PU i loaʻa ma ka hoʻohui ʻana i kahi polyol kaulahao lōʻihi me ka isocyanate ua hoʻohana ʻia ma ke ʻano he ʻāpana palupalu, a ʻo ka PU i loaʻa ma ka hoʻohui ʻana i kahi diol kaulahao pōkole me ka isocyanate ua hoʻohana ʻia ma ke ʻano he ʻāpana paʻakikī.

ʻO nā noi o nā TPU elastomers i nā uea a me nā kaula e pili nui ana i nā kahua aʻe:

·Kame uea kaʻa: Kame uea ʻōnaehana Anti-lock (ABS), uwea odometer, uwea kamaʻilio kaʻa, uwea ʻūpā lapalapa hoʻouka, a pēlā aku.

·Nā kaula ʻimi honua: nā kaula ʻimi kahua ʻaila\moana\ʻāina, nā kaula ʻike nalu seismic, a pēlā aku;

·Nā uea uila o ka mea kūʻai aku: uwea headphone, (mea pale ahi) Uea ʻIkepili no ka hoʻouka ʻana i ke kelepona paʻalima, uwea leo, uwea USB, uwea lako kamepiula, a pēlā aku;

03 Hoʻohālikelike i ka hana o nā mea uea a me nā kaula TPE a me TPU

(1) ʻOi aku ka ikaika o ka TPU ma mua o ka TPE, ka ikaika tensile a me ka wikiwiki elongation: ʻO ka ikaika tensile o TPU he 2 a 3 mau manawa o ka rubber kūlohelohe a me ka rubber synthetic, a he maikaʻi ke kūlou o ka TPU; maikaʻi ke kūʻē ʻana i ke kapa komo, ʻo ka waiwai o ka Taber wear he 0.35-0.5mg, ʻo ia ka mea liʻiliʻi loa ma waena o nā plastics, no laila he maikaʻi ke kūʻē ʻana i ka haki ʻana o ka ʻili.

(2) Manaʻo TPE a me TPU a me ka hana palupalu: Hiki iā TPE ke hoʻoponopono i ka paʻakikī a me ka maʻalahi mai kahi ākea o 0 degere a i 99A, ʻoiai ʻo ka pae paʻakikī o TPU he 60 ~ 95A, a mālama mau ia i ka elasticity ke ʻoi aku ka paʻakikī ma mua o 85A. He ʻano kēia ʻaʻole i loaʻa i nā elastomers ʻē aʻe, no laila he kiʻekiʻe ke kākoʻo ukana o TPU a me ka hopena omo a hoʻokuʻu maikaʻi; ʻokoʻa loa ka manaʻo o nā mea ʻelua i nā pae paʻakikī like ʻole, a hoʻololi ia i nā manawa like ʻole e like me nā koi; Loaʻa iā TPE kahi pohō elastic nui i nā manawa paʻakikī kiʻekiʻe.

(3) He maikaʻi ke kūpaʻa wai o ka Polyether TPU a me TPE, akā he haʻahaʻa ke kūpaʻa wai o ka polyester TPU; ʻOi aku ka maikaʻi o ke kūpaʻa aila o ka TPU ma mua o ka TPE.

(4) ʻO ke kūpaʻa UV o ka polyester TPU he haʻahaʻa iki a he maʻalahi hoʻi i ka melemele. No ka mea, ua hui pū ʻia ke apo benzene o ka ʻāpana paʻakikī polyurethane a me ka mea hoʻōla ʻala me ka ester carboxylic acid, hana ʻia kahi oxidation a me ka hoʻonohonoho hou ʻana, e hana ana i kahi ʻano quinone me nā hui chromogenic, a laila e hana ana i kahi pilina unsaturated i loko o ka ʻāpana polymer; ma lalo o ka hana a nā kukuna ultraviolet, hāʻawi ʻia ka ikehu "free radicals" no ka hopena hoʻololi kala, kahi e hāʻawi ai i ka ikehu lawa e luku ai i nā pilina kemika o ka hapa nui o nā polymers, hoʻoulu i kahi hopena oxidation aunoa, a hoʻoulu i ka ʻelemakule a me ka degradation.

ʻOi aku ka maikaʻi o ka hana melemele o ka polyether TPU ma mua o ka polyester TPU. Hiki iā ia ke hoʻomaikaʻi i ka hiki ke anti-UV ma hope o ka hoʻololi ʻana, e hōʻoia ana ʻaʻole ia e melemele i loko o 1 a 2 mau makahiki. ʻOi aku ka maikaʻi o ka anti-UV o TPE ma mua o ka TPU, no laila ʻoi aku ka maikaʻi o ka TPE pale kala ma mua o ka TPU.

I ka hōʻuluʻulu ʻana, loaʻa i ka polyether TPU nā pono o ke kūpaʻa hydrolysis, ke kūpaʻa mildew, ke kūpaʻa kiʻekiʻe a me ka hana haʻahaʻa haʻahaʻa. Loaʻa i nā Polyester TPU nā pono o ka ikaika tensile kiʻekiʻe, ka maʻalahi, ke kūpaʻa ʻaʻahu, ke kūpaʻa solvent, ke kūpaʻa oxidation a me ke kūpaʻa wela kiʻekiʻe.

04 Ka hana ʻana a me ke kūkulu ʻana i nā mea uea a me nā kaula TPE a me TPU a me ka hoʻohālikelike kumukūʻai

Hoʻohālikelike ʻana o ka hana ʻana a me ke kūkulu ʻana o ka uea TPE a me TPU a me nā mea uwea:

(1) He maʻalahi loa ka TPU e omo i ka wai. Pono e hoʻomaloʻo ʻia ma 100℃*3~4H ma mua o ka hana ʻana, ʻoiai ʻo TPE e hoʻomaloʻo ʻia ma 70~80℃*2H;

(2) Nā koi TPU no nā mea hoʻopuka. ʻO nā mea hoʻopuka ʻekolu pae hoʻokahi me ka lakio L/D ma waena o 20-30 a me ka lakio compression ma waena o 2-4 he kūpono no ka hana ʻana o TPU; ʻo ka hakahaka ma waena o nā wili a me nā paipu mea ma kahi o 0.1-0.2mm. Pono ka hoʻolālā wili kūpono e pale i ka friction nui a me ka wela nui, e hoʻoulu ai i ka palaho a me ka haki ʻana o ka mea, a laila e hōʻemi ana i nā waiwai mechanical o ka huahana.

Aia ka wikiwiki o ka wili ma ke anawaena o ka wili. ʻOiai he maʻalahi ka TPU i ka palai ʻana a me ka ʻoki ʻana, hiki i ka wikiwiki kiʻekiʻe loa ke alakaʻi maʻalahi i ka haki ʻana o ka TPU. Inā haʻahaʻa loa ia, e alakaʻi pū ia i ka haki ʻana ma muli o ka manawa noho lōʻihi. Ma ke ʻano laulā, ua hoʻonohonoho ʻia ka wikiwiki o ka wili ma ka pae o 25-60rpm, ʻoiai ʻo TPE e koi ana i kahi extruder palupalu.

(3) Ma mua o ka hoʻomaka ʻana i ka TPU, e hōʻoia i ka hoʻomaʻemaʻe ʻia ʻana o ka wili, ke poʻo mīkini a me ka cylinder wili me nā kihi make ʻole. Ua pau nā hoʻomākaukau āpau, e like me ka hoʻomākaukau ʻana i ka huahana semi-finished, ka paʻi ʻana a me ka debugging, a pēlā aku. ʻO ka hana hope loa, ʻo ia ka wehe maoli ʻana i ka huahana i hoʻopau ʻia ma mua o ka huki ʻana i ka hopper e hoʻokuʻu i ka mea i ka wili. I ke kahua mua o ka hoʻomaka ʻana o ka mīkini, e hoʻāʻo e hoʻemi i ka manawa noho o ka rubber ma ka wili. Ma hope o ka hoʻokuʻu ʻia ʻana o ka mea, e hoʻomaka koke ʻia ka mīkini i loko o 5 mau minuke. Pono e mālama pono ʻia kēia wā koʻikoʻi i ka hoʻomaka ʻana. E hoʻolohe i ke kauoha, a e loaʻa iā ʻoe ka hopena pālua me ka hapalua o ka hoʻoikaika.

(4) ʻAʻole ʻoluʻolu ka TPE i ka ʻoki ʻana, a ʻaʻole e pala maʻalahi inā noho lōʻihi. He ʻoi aku ka maʻalahi o ka hana ʻana.

Hoʻohālikelike ʻana i nā kumukūʻai hana o nā mea uea a me nā kaula TPE a me TPU:

(1) ʻAʻole ʻokoʻa loa ke kumukūʻai o ka mea TPE a me ka polyester TPU. ʻOi aku ke kiʻekiʻe o ka Polyester TPU, akā kiʻekiʻe ke kumukūʻai o ka polyether TPU.

(2) ʻO nā mea ʻekolu ka haʻahaʻa loa o ka TPE density, ukali ʻia e ka polyether TPU density, a me ka polyester TPU density nui loa, a me ke kumukūʻai haʻahaʻa loa o ka hoʻohana ʻana i ka TPE.

Ma ka hoʻohālikelike ʻana i nā waiwai kumu o nā mea TPE a me TPU a me ka ʻenehana hana mea, loaʻa i nā mea ʻelua ko lākou mau pono a me nā hemahema. Eia nō naʻe, mai ka nānā ʻana i nā kaulahao ʻoihana TPU kūloko a me TPE, ʻoi aku ka paʻa a me ka maʻalahi o ke kahawai mākeke mea maka TPE, ʻoiai ʻo ka hapa nui o nā mea maka hana TPU e hilinaʻi nei i nā mea lawe mai, a he ʻano hope ke kaʻina hana kūloko, no laila he paʻakikī ke hōʻoia i ka paʻa o ka huahana. He ʻokoʻa loa nā ʻano mea maka o kēlā me kēia mea hana. Pono kā mākou mau hoa elastomer e hoʻomaopopo i ka lawa e hoʻomaʻamaʻa i ka hoʻomohala ʻana i ka noi a me ka hoʻololi ʻana.

Ma o ka ʻimi hohonu ʻana i ke ʻano o loko o ka mea, ka nānā ʻana i nā loli hana i ka manawa maoli a me ka ʻike mau ʻana i ke kūpaʻa, ua hōʻike ʻia ka kūlike a me ke kūpaʻa o nā uea ma lalo o nā wahi kai ʻino. Ke nānā nei i mua i ka wā e hiki mai ana, ʻo ka hoʻomaikaʻi mau ʻana o ka mea a me ke ʻano o nā laina hoʻoili kai e hoʻokumu i kahi kahua paʻa no ka eli ʻana a me ka hoʻohana ʻana i nā waiwai kai.
