Bambanci tsakanin TPU polyester da polyether, da dangantaka tsakaninPolycaprolactone TPU
Na farko, bambanci tsakanin TPU polyester da polyether
Thermoplastic polyurethane (TPU) wani nau'i ne na kayan elastomer mai girma, wanda aka yi amfani da shi sosai a fannoni daban-daban. Dangane da tsarin daban-daban na sashinta mai laushi, ana iya raba TPU zuwa nau'in polyester da nau'in polyether. Akwai bambance-bambance masu mahimmanci a cikin aiki da aikace-aikace tsakanin nau'ikan biyu.
Polyester TPU yana da ƙarfi mai ƙarfi da juriya, juriya mai ƙarfi, kaddarorin lanƙwasa da juriya mai ƙarfi suna da kyau sosai.

Duk da haka, juriya na hydrolysis na polyester TPU ba shi da kyau, kuma yana da sauƙi don mamayewa ta hanyar kwayoyin ruwa da karaya.
Da bambanci,Polyether TPUan san shi don ƙarfin ƙarfinsa, juriya na hydrolysis da babban ƙarfin hali. Ƙarfin aikin sa yana da kyau sosai, dace da amfani a cikin yanayin sanyi. Koyaya, ƙarfin kwasfa da ƙarfin karyewar polyether TPU yana da rauni kaɗan, kuma juriya, lalacewa da tsagewar polyether TPU shima ƙasa da na polyester TPU.
Na biyu, da polycaprolactone TPU
Polycaprolactone (PCL) abu ne na musamman na polymer, yayin da TPU gajere ne don polyurethane thermoplastic. Kodayake su duka kayan polymer ne, polycaprolactone kanta ba TPU ba ce. Duk da haka, a cikin tsarin samar da TPU, ana iya amfani da polycaprolactone azaman muhimmin sashi mai laushi don amsawa tare da isocyanate don samar da TPU elastomers tare da kyawawan kaddarorin.
Na uku, dangantaka tsakanin polycaprolactone daBabban darajar TPU
Masterbatch yana taka muhimmiyar rawa wajen samar da TPU. Masterbatch shine babban mai haɓakawa mai mahimmanci, yawanci ya ƙunshi nau'ikan abubuwa daban-daban kamar su polymer, plasticizer, stabilizer, da sauransu.
A matsayin babban kayan aikin polymer, ana amfani da polycaprolactone azaman muhimmin bangaren TPU masterbatch. By prepolymerization na polycaprolactone tare da sauran aka gyara, TPU kayayyakin da kyau kwarai inji Properties, hydrolysis juriya da kuma low zazzabi juriya za a iya shirya. Waɗannan samfuran suna da fa'idodin aikace-aikacen da yawa a cikin fa'idodin tufafi marasa ganuwa, kayan aikin likita, takalman wasanni da sauransu.
Na hudu, halaye da aikace-aikacen polycaprolactone TPU
Polycaprolactone TPU yayi la'akari da fa'idodin polyester da polyether TPU, kuma yana da mafi kyawun kaddarorin. Ba wai kawai yana da ƙarfin ƙarfin injiniya da juriya ba, amma kuma yana nuna kyakkyawan juriya na hydrolysis da ƙarancin zafin jiki. Wannan ya sa polycaprolactone TPU yana da tsawon rayuwar sabis da kwanciyar hankali a cikin hadaddun yanayi da canzawa.
A cikin filin tufafin da ba a iya gani ba, polycaprolactone TPU ya zama kayan da aka fi so saboda kyawawan abubuwan da suka dace. Zai iya tsayayya da lalacewar abubuwan waje kamar ruwan acid, ƙura, zubar da tsuntsaye, da tabbatar da aiki da rayuwar tufafin mota. Bugu da ƙari, a fagen na'urorin kiwon lafiya, kayan wasanni, da dai sauransu, polycaprolactone TPU ya kuma sami kulawa mai yawa don aminci da amincinsa.
A takaice, akwai manyan bambance-bambance tsakanin TPU polyester da polyether a cikin aiki da aikace-aikace, yayin da polycaprolactone, a matsayin ɗaya daga cikin mahimman abubuwan TPU, yana ba da samfuran TPU kyawawan kaddarorin abubuwa. Ta hanyar zurfin fahimtar alaƙa da halaye tsakanin waɗannan kayan, za mu iya zaɓar mafi kyawun zaɓi da amfani da samfuran TPU masu dacewa don saduwa da buƙatun filayen daban-daban.
