03 Kwatanta aikin kayan waya da kebul na TPE da TPU

(1) TPU tana da ƙarfi mafi kyau fiye da TPE, ƙarfin tauri da kuma tsawon tsayi: Ƙarfin tauri na TPU ya ninka na roba na halitta da robar roba sau 2 zuwa 3, kuma TPU tana da juriya mai kyau ta lanƙwasa; juriya mai kyau tauri, ƙimar taber tauri shine 0.35-0.5mg, wanda shine mafi ƙanƙanta a cikin robobi, don haka yana da juriya mai kyau ta karye fata.

(2) Ji da TPE da TPU da aiki mai laushi: TPE na iya daidaita tauri da sassauci daga nau'ikan digiri 0 zuwa 99A, yayin da kewayon tauri na TPU shine 60~95A, kuma har yanzu yana riƙe da sassauci lokacin da tauri ya wuce 85A. Wannan siffa ce da sauran elastomers ba su da ita, don haka TPU tana da ƙarfin tallafi mai yawa da kuma kyakkyawan tasirin tsotsa da fitarwa; jin da suke yi ya bambanta sosai a cikin nau'ikan tauri daban-daban, kuma yana daidaitawa da lokatai daban-daban bisa ga buƙatu; TPE yana da babban asarar roba a lokutan tauri mai yawa.

(3) Polyether TPU da TPE suna da juriyar ruwa mai kyau, amma polyester TPU ba ta da juriyar ruwa mai kyau; TPU tana da juriyar mai mafi kyau fiye da TPE.

(4) Juriyar UV ta polyester TPU ba ta da kyau kuma tana da saurin yin rawaya. Saboda zoben benzene na ɓangaren polyurethane mai tauri da kuma maganin warkar da ƙanshi suna haɗuwa da carboxylic acid ester, akwai oxidation da sake tsarawa, suna samar da tsarin quinone tare da ƙungiyoyin chromogenic, ta haka ne ke haifar da haɗin da ba shi da cikakken cikawa a cikin ɓangaren polymer; a ƙarƙashin tasirin hasken ultraviolet, ana samar da makamashi "free radicals" don amsawar canjin launi, wanda ke samar da isasshen kuzari don lalata haɗin sinadarai na yawancin polymers, yana haifar da amsawar oxidation ta atomatik, kuma yana haifar da tsufa da lalacewa.

Aikin canza launin rawaya na polyether TPU ya fi na polyester TPU kyau. Yana iya inganta ƙarfin hana UV bayan an gyara shi, yana tabbatar da cewa bai canza launin rawaya cikin shekaru 1 zuwa 2 ba. Maganin hana UV na TPE gabaɗaya ya fi na TPU kyau, don haka TPE mai jure launi ya fi na TPU kyau.

A taƙaice dai, polyether TPU yana da fa'idodin juriyar hydrolysis, juriyar mildew, juriya mai yawa da ƙarancin aikin zafin jiki. Polyester TPUs suna da fa'idodin ƙarfin juriya mai yawa, sassauci, juriyar lalacewa, juriyar narkewa, juriyar iskar shaka da kuma juriyar zafin jiki mai yawa.

04 Sarrafa da ƙirƙirar kayan waya da kebul na TPE da TPU da kwatancen farashi

Kwatanta sarrafa da samar da kayan waya da kebul na TPE da TPU:

(1) TPU yana da sauƙin sha ruwa. Yana buƙatar a busar da shi a 100℃*3~4H kafin a sarrafa shi, yayin da TPE ke busar da shi a 70~80℃*2H;

(2) Bukatun TPU ga masu fitar da kaya. Masu fitar da kaya masu matakai uku masu sukurori ɗaya tare da rabon L/D tsakanin 20-30 da rabon matsi tsakanin 2-4 sun dace da sarrafa TPU; gibin da ke tsakanin sukurori da bututun kayan shine kusan 0.1-0.2mm. Tsarin sukurori mafi kyau ya kamata ya guji gogayya mai tsanani da zafi fiye da kima, wanda ke sa kayan su ruɓewa da fashewa, ta haka ne rage halayen injinan samfurin.

Saurin sukurori ya dogara ne da diamita na sukurori. Tunda TPU tana da saurin soya da yankewa, saurin da ya yi yawa zai iya haifar da fashewar TPU cikin sauƙi. Idan ya yi ƙasa da haka, zai kuma haifar da tsagewa saboda tsawon lokacin da ake ɗauka. Gabaɗaya, saurin sukurori yana tsakanin 25-60rpm, yayin da TPE ke buƙatar na'urar fitar da iska mai laushi.

(3) Kafin fara TPU, tabbatar an tsaftace sukurori, kan injina da silinda sukurori ba tare da kusurwoyi marasa kyau ba. An kammala duk shirye-shirye, kamar shirya samfurin da aka gama, bugawa da gyara kurakurai, da sauransu. Mataki na ƙarshe shine a buɗe samfurin da aka gama kafin a ja hopper don sakin kayan zuwa sukurori. A matakin farko na fara injin, yi ƙoƙarin rage lokacin zama na robar akan sukurori. Bayan an cire kayan, za a fara injin cikin sauri cikin mintuna 5. Dole ne a kula da wannan muhimmin lokaci da kyau a farkon. Kula da oda, kuma za ku sami ninki biyu na sakamakon tare da rabin ƙoƙarin.

(4) TPE ba ta da saurin yankewa, kuma ba za ta ruɓe cikin sauƙi ba idan ta daɗe. Ya fi dacewa a sarrafa shi.

Kwatanta farashin sarrafawa na kayan waya da kebul na TPE da TPU:

(1) Farashin kayan TPE da polyester TPU ba su da bambanci sosai. Polyester TPU ya ɗan fi girma, amma farashin polyether TPU yana da tsada sosai.

(2) Uku suna da mafi ƙarancin yawan TPE, sai kuma yawan polyether TPU, da kuma mafi girman yawan polyester TPU, da kuma mafi ƙarancin farashin amfani da TPE.

Ta hanyar kwatanta muhimman halaye na kayan TPE da TPU da fasahar sarrafa kayan aiki, duka suna da nasu fa'idodi da rashin amfani. Duk da haka, daga nazarin sarƙoƙin masana'antar TPU da TPE na cikin gida, hanyar kasuwar kayan TPE ta fi kwanciyar hankali da dacewa, yayin da yawancin kayan samar da TPU suka dogara da shigo da kaya, kuma tsarin samar da kayan cikin gida yana da koma baya, don haka tabbatar da daidaiton samfura yana da wuya. Halayen kayan da aka samar na kowane masana'anta sun bambanta sosai. Abokan hulɗarmu na elastomer suna buƙatar fahimtar isa don sauƙaƙe aikace-aikace da haɓaka gyare-gyare.

Ta hanyar zurfafa bincike kan tsarin ciki na kayan, sa ido kan canje-canjen aiki a ainihin lokaci da kuma ci gaba da gano kwanciyar hankali, ana nuna daidaito da juriyar wayoyi a ƙarƙashin yankunan teku masu tsauri. Idan aka yi la'akari da makomar, ci gaba da inganta kayan da tsarin layukan watsawa na ƙarƙashin ruwa zai zama ginshiƙi mai ƙarfi ga hakar ma'adinai da amfani da albarkatun ruwa.
