Me ka sani game da kebul na polyurethane? (TPU cable)

Kebul na Polyurethanes suna nufin kebul waɗanda ke amfani da kayan polyurethane a matsayin rufi ko sheath. Juriyar lalacewa mai ƙarfi tana nufin juriyar lalacewa mai ƙarfi na sheath na kebul da Layer na rufi.

 

Kayan polyurethane da ake amfani da su a cikin kebul ana kiransu da TPU, wanda shine robar polyurethane mai amfani da thermoplastic elastomer. An raba shi galibi zuwa nau'in polyester da nau'in polyester, tare da kewayon tauri (60HA-85HD), mai jure lalacewa, mai jure mai, mai haske da roba. TPU ba wai kawai yana da kyawawan halaye masu jure lalacewa, mai jure tashin hankali, mai jure tashin hankali, mai ƙarfi da tsufa ba, har ma yana da kayan da suka dace da muhalli.

 

A yau, Lansheng Cable zai jagorance ku ta cikin manyan fasaloli guda 8 da wuraren amfani da kebul na polyurethane.

 

Manyan siffofi guda 8:

1. Juriyar lalacewa

 

Idan kebul ɗin ya sha wahala wajen aiki kamar gogayya, karcewa da niƙawa yayin amfani da shi, zai sa saman sa ya lalace a hankali, don haka sauƙin amfani da zaɓin kayan yana da matuƙar muhimmanci.

 

Kayan da aka yi da filastik na TPU suna da juriyar lalacewa mai kyau kuma suna da juriyar lalacewa fiye da igiyoyin roba na halitta sau biyar. Suna ɗaya daga cikin kayan da aka fi zaɓa don samfuran da ba sa jure lalacewa.

 

2. Aikin tensile

 

Ƙarfin taurin kebul na polyurethane ya kai har zuwa 38MPa, kuma ƙarfin taurin kebul na roba na yau da kullun (ɗaya daga cikin kebul da aka fi sani a kasuwa) shine 8-12MPa kawai.

 

Idan aka yi amfani da kebul a cikin yanayi mai jan hankali, murfin kebul mai harsashi na roba ba shi da tasirin jan hankali, kuma zuciyar tana karyewa cikin sauƙi bayan an fuskanci matsin lamba daga waje. Kyakkyawan juriyar jan hankali na murfin kebul na polyurethane da rufin yana taka rawa mai kyau a kan tsakiyar waya, yana sa ya daɗe kuma ya daɗe.

 

3. Yage aikin

 

Ƙarfin tsagewa shine ikon kayan don tsayayya da tsagewa. Gabaɗaya, TPU yana da juriya mai ƙarfi, kuma ƙarfin tsagewa yana da kyau sosai idan aka kwatanta da wasu roba da filastik da aka saba amfani da su.

 

4. Gyaran aiki

 

Yawancin kebul na filastik (kamar RVV) suna iya karyewa sakamakon matsin lamba na lokaci-lokaci. Kebul ɗin polyurethane na iya kiyaye juriya mai kyau ga lanƙwasawa a ƙarƙashin yanayi daban-daban, wanda hakan ya sa su zama ɗaya daga cikin mafi kyawun zaɓuɓɓuka don yanayin lanƙwasawa akai-akai.

 

5. Juriyar Hydrolysis

 

Kebul ɗin polyurethane suna da juriya mai kyau ga ruwa a ƙarƙashin turbidity, kuma ba za su fuskanci hydrolysis a bayyane ba cikin shekaru 1 zuwa 2, musamman jerin polyether sun fi kyau.

 

6. Juriyar zafin jiki mai yawa da juriyar iskar shaka

 

Gabaɗaya, kayan filastik ana iya yin oxidize cikin sauƙi a cikin yanayi sama da 70℃ na dogon lokaci, kuma TPU yana da kyakkyawan ikon hana tsufa; gabaɗaya, juriyar zafin jiki na TPU na iya kaiwa 120℃.

 

7. Juriyar Mai da kuma kaddarorin juriyar magani

 

TPU wani abu ne mai ƙarfi na polymer wanda ba shi da alaƙa da man fetur mara polar kuma kusan ba ya lalata a cikin man fetur (kamar man fetur, fetur) da man fetur na injiniya (kamar man hydraulic, man injin, man shafawa, da sauransu); daga cikinsu, samfuran jerin polyester sun fi kyau a cikin kebul na polyurethane.

 

8. Ƙarancin zafin jiki

 

Kebulan polyurethane suna da juriya mai kyau ga yanayin zafi kuma yawanci suna kaiwa -50℃. Suna iya maye gurbin fannoni daban-daban inda ba za a iya amfani da kebul na PVC da roba ba saboda ƙarancin karyewar zafin jiki. Sun dace musamman ga kebul da ake amfani da su a wurare masu sanyi sosai.
