Codsiga TPU sida Flowxirininiyrim

Si loo yareeyo kharashaadka badeecada oo ay ku helaan wax qabad dheeri ah,polyurethane themoplasticCudur-yaqaannada waxaa loo isticmaali karaa sida wakiilada ugu adag ee loo adeegsado si adag u adkeeya meelaha kala duwan ee loo yaqaan 'themoplastlast' iyo waxyaabo caag ah oo wax laga beddelay.

Sababo la xiriirapolyurethaneNoqoshada polymer polymol-ka sarreeya, waxay la jaan qaadi kartaa poly polysing ama polar-ka oo la jaan qaadaya polar. Isku-darka abs waxay ku beddeli kartaa isticmaalka balaastigga injineernimada. Markii loo isticmaalo isku darka polycarbonate (PC), waxay leedahay guryo ay ka mid yihiin caabbinta saliida, iska caabbinta shidaalka, iyo iska caabbinta saamiga, waxaana loo isticmaali karaa in lagu sameeyo jirka gaariga; Ku qasitaanka polyester wuxuu hagaajin karaa bandhigiisa adag; Intaas waxaa sii dheer, waxay si fiican ula jaan qaadi kartaa polyvinyl chloride, pololoxymymerene (pom), ama chloyvinylide chloride; Polyester Polyrethane waxay si fiican ula jaan qaadi kartaa 15% caagga nafijka ama 40% nadaafadda caagga ah ee caagga ah ee caagga ah ee chloride chloride chloride ' Polythertherthane sidoo kale waxay ku habboonaan kartaa 40% nitrile caag (polyvinyl chloride chloride chloride chloresive; Waxay sidoo kale la jaan qaadi kartaa acrylonitrile styrene (San) Copoyms; Waxay sameyn kartaa qaab dhismeedka shabakadda ee is-dhexgalka (IPN) oo leh polysilosanes falcelinta. Intooda badan inta badan waxyaabaha kor ku xusan ee ku xusan dhallaanka isku dhafka ah ayaa horey loo soo saaray si rasmi ah.
Sanadihii la soo dhaafay, waxaa soo kordhay tiro cilmi baaris ah oo ku saabsan xasaasiyadda siidaynta ee pom byTuneShiinaha. Isku-darka TPU iyo POM kaliya waxay wanaajisaa kaliya iska caabbinta heerkulka sare iyo astaamaha farsamada ee TPU, laakiin sidoo kale si weyn ayey u adkaysaa POM. Baarayaasha qaar baa muujinaya in baaritaannada jabka jabsan, marka la barbar dhigo pom matrix, pom-ka pom oo leh dheelitirka TPU ee loo maro kala-guurka jabka jabka jabka. Ku darista TPU waxay sidoo kale dhalisaa pom oo leh qaab qaab fikir xusuus ah. Gobolka Crystallo ee Pom wuxuu u adeegaa sidii wajiga go'an ee qaabka qaabka loo yaqaan 'alkoys', halka gobolka amorphphous ee amoropous tpu iyo pom ay u adeegtaa wajiga dib loo rogi karo. Marka heerkulka jawaabta soo kabashada uu yahay 165 ℃ oo waqtiga soo kabashada ay tahay 120 s, heerka soo kabashada ee alkolada ayaa gaadhay in ka badan 95%, iyo saameynta soo kabashada ayaa ugu fiican.
TPU way adagtahay in la la jaan qaado agabyada polar-ka ah ee aan ahayn sida polytylne, polypropylene, poltyrenepleent, caag caag ah, ama budada caagga caagga ah, mana soo saari karaan agabyada isku-darka leh waxqabadka wanaagsan. Sidaa darteed, qaababka daaweynta dusha sare sida plasma, corona dheecaanka corona, kimistariga qoyan, preter, olol, ama gaasaska falcelinta ayaa badanaa loo isticmaalaa kan dambe. Tusaale ahaan, alaabada hawada Mareykanka iyo shirkadaha kiimikada si weyn ayey u horumarin karaan miraha foosha, oo ay u xidhaan caabbinta molteceelne-ka moliculal-molicular ee molteculal-ka moluculal-ka ah oo ah 3-5 milyan ka dib markii loo yaqaan 'polyurethane' oo ku saabsan saamiga 10% ah. Intaa waxaa dheer, in F2 / O2 ee loo yaqaan 'gaaska gaaska' ee firfircoon ayaa lagu dabaqi karaa fiber-ka gaaska gaagaaban ee ku saleysan dhererkiisu yahay 6-35mm oo kor lagu soo sheegay, kaas oo kor u qaadi kara adkaanta iyo adkeynta ilmada ee sheyga isku-darka ah.
