Xyoo 1958, Goodrich Tshuaj Hluav Taws Xob (tam sim no tau muab cov npe ntawm TPU Hom Brandu thawj zaug. Txij li 40 xyoo dhau los, muaj ntau tshaj 20 hom npe npe thoob ntiaj teb, thiab txhua hom muaj ntau hom khoom. Tam sim no, TPU cov khoom siv raw khoom lag luam tsuas yog suav nrog Basf, lubrichua tshuaj lom neeg, Shanghai Heng'an, Ruihua, Xuchuan tshuaj, thiab lwm yam.
1, Qeb ntawm TPU
Raws li cov qauv Segment Segment, nws tuaj yeem faib ua hom qib polyester, thiab pawg tab sis pab pawg, lossis pawg butene pab pawg.
Raws li cov qauv segment nyuaj, nws tuaj yeem faib ua qhov ua kom muaj zog thiab koj txoj kev ua kom muaj kev sib tw glycoling extenders lossis txoj saw diam ntxiv. Cov kev faib tawm ib txwm tau muab faib ua hom polyester thiab hom polyether.
Raws li lub xub ntiag lossis tsis muaj kev sib txuas ntawm kev sib txuas lus, nws tuaj yeem faib ua cov ntshiab thermoplastic thiab semi thermoplastic.
Tus qub qub muaj cov qauv zoo nkauj thiab tsis muaj kev sib txuas sib txuas; Cov tom kawg muaj ib qho me me ntawm kev sib txuas sib txuas xws li Allophancic Acid Ester.
Raws li kev siv cov khoom tiav, lawv tuaj yeem muab faib ua profiled feem (share (nplooj ntawv, cov nplaum, cov nplaum, thiab lwm yam.
2, synthesis ntawm tpu
TPU belongs rau polyurethane nyob rau hauv cov nqe lus ntawm cov qauv molecular. Yog li, nws tau ua li cas?
Raws li cov txheej txheem sib txawv sib txawv, nws feem ntau muab faib ua cov polymerization thiab tov polymerization.
Hauv cov polymerization, nws kuj tuaj yeem muab faib ua cov qauv ua ntej polymerization thiab ib qho txheej txheem ib qib zuj zus raws li lossis tsis muaj kev tawm tsam ua ntej:
Txoj kev npaj ua ntej yuav cuam tshuam nrog riiscyanate nrog macromolecular diols rau qee lub sijhawm ua ntej ntxiv cov saw txuas ntxiv los tsim TPU;
Ib-kauj ruam qauv cuam tshuam nrog ib txhij sib xyaw thiab rov ua kom haum macromolecular diols, thiab saw txuas rau tsim TPU.
Tshuaj Polymerization cuam tshuam nrog ua ntej Diisocyananate hauv cov kuab tshuaj, tom qab ntawd ntxiv cov saw txuas ntxiv los tsim TPU.
Hom kev sib tw TPU, hnyav, nyuaj lossis TPU sensitation lub xeev tuaj yeem cuam tshuam txog kev kwv yees li ntawm 1.10-1.25, thiab tsis muaj qhov sib txawv piv rau lwm cov ntaub qhwv thiab plastics.
Ntawm tib lub hardness, lub ntom ntawm polyether hom TPU yog qis dua li ntawm Polyester Hom TPU.
3, Kev Ua Tpu
TPU hais kom muaj ntau cov txheej txheem los ua cov khoom kawg, feem ntau yog siv cov kev daws teeb meem thiab kev daws teeb meem rau TPU ua.
Kev ua cov txheej txheem melting yog ib qho kev siv yas ua hauv kev lag luam yas, xws li kev sib xyaw, dov, tshuab moulding, thiab moulding;
Kev ua yog cov txheej txheem ntawm kev txhawb kev daws los ntawm kev daws cov kuab tshuaj lossis cov polymerizing ncaj qha, thiab tom qab ntawd txheej, kiv, tig mus.
Cov khoom kawg tau ua los ntawm TPU feem ntau tsis tas yuav muaj kev txwv tsis pub muaj volcanization cov tshuaj tiv thaiv, uas tuaj yeem ua rau cov khoom siv me me ua kom luv dua.
4, kev ua tau zoo ntawm TPU
TPU muaj cov high modulus, siab lub zog, siab elongation thiab elasticity thiab elasticity, cov roj ua tsis kam, thiab kev laus tsis kam.
High tensile lub zog, siab elongation, thiab qis-lub sij hawm ntev kev deformation muaj txhua qhov tseem ceeb ntawm TPU.
Xiaou yuav yog medaborate ntawm cov neeg kho tshuab ntawm TPU ntawm TPU ntawm TPU ntawm TPU ntawm TPU ntawm TPU ntawm TPU ntawm TPU ntawm TPU ntawm Tensile lub zog thiab elongation, resilience, nyuaj, thiab lwm yam.
High tensile lub zog thiab elongation siab
TPU muaj lub zog zoo tshaj plaws lub zog thiab elongation. Los ntawm cov ntaub ntawv hauv daim duab hauv qab no, peb tuaj yeem pom tias lub zog tensile thiab elongation ntawm polyether hom TPU yog qhov zoo dua li cov polyvinyl chloride yas thiab roj hmab.
Tsis tas li ntawd, TPU tuaj yeem ua kom tau raws li cov kev cai ntawm kev lag luam khoom noj nrog me me lossis tsis muaj kev sib ntxiv ntxiv, uas tseem nyuaj rau lwm cov ntaub ntawv xws li PVC thiab roj hmab kom ua tiav.
Resilience yog heev rhiab rau qhov kub
Lub Neej Ntawm TPU yog hais txog qib uas nws tau sai sai rau nws cov kev ntxhov siab tom qab deformation excomple excomple extraction ua haujlwm rau kev ua haujlwm yuav tsum tau tsim deformation. Nws yog ib qho haujlwm ntawm cov qauv hloov pauv thiab kev sib txhuam sab hauv ntawm ib lub cev elastic thiab yog heev rhiab rau qhov kub.
Qhov rov qab los txo qis nrog qhov ntsuas kub kom txog thaum muaj qhov kub thiab txias, thiab cov elasticity sai dua. Qhov ntsuas kub no yog cov crystallization kub ntawm cov ntu muag, uas tau txiav txim siab los ntawm cov qauv ntawm macromolecular diol. Polyether Hom TPU yog qis dua polyester hom TPU. Ntawm qhov kub hauv qab no lub crystallization kub, tus elastomer ua nyuaj heev thiab loses nws elasticity. Yog li ntawd, resilisence yog zoo li ib tug remound los ntawm saum npoo ntawm cov hlau tawv.
Lub hardness ntau yog ntug dej A60-D80
Hardness yog qhov ntsuas ntawm cov khoom muaj peev xwm tiv thaiv deformation, kev nce qib, thiab khawb.
Lub hardness ntawm TPU feem ntau yog ntsuas siv dej hiav txwv A thiab ntug dej D tawvfness D tawv ncauj, nrog ntug dej rau softer tpus thiab ntug dej d siv rau harder tpus.
Lub hardness ntawm TPU tuaj yeem hloov kho los ntawm kev kho cov feem ntawm cov ntaub mos mos muag thiab nyuaj ntu. Yog li, TPU muaj ntau yam kev nyuaj, xws li los ntawm ntug dej A60-D80, kev elevelity thoob plaws tag nrho cov hardness ntau.
Raws li kev nyuaj hloov pauv, qee cov khoom ntawm TPU yuav hloov. Piv txwv li, nce lub hardness ntawm TPU yuav ua rau kev hloov pauv tensile thiab rhuav lub ntom ntom, nce ntom ntom ntom ntom, thiab cov cua kub ua kom muaj zog.
5, Daim ntawv thov ntawm TPU
Raws li ib tug zoo heev elastomer, TPU muaj ntau yam hauv cov khoom siv hauv qab cov khoom siv hauv qab, cov khoom ntaus pob ncaws pob, khoom ua si, thiab lwm daim teb.
Khau Khau Khoom
TPU yog tsuas yog siv rau cov khau khau vim nws zoo elasticity thiab hnav tsis kam. Cov khoom lag luam khau uas muaj TPU yog qhov zoo dua zoo dua li cov khoom siv khau ua ke, yog li lawv tau siv khau khiab ntau dua, tshwj xeeb yog cov khau ua kis las thiab khau uas muaj xws li.
txoj hlua yas
Vim nws cov muag muag, lub zog zoo tensile, cuam tshuam lub zog, thiab roj hoses thiab roj hoses thiab roj hoses thiab roj hoses, tsheb hlau, tsheb, thiab tshuab cov cuab yeej siv hluav taws xob, thiab tshuab cov cuab yeej siv hluav taws xob, thiab tshuab cov cuab yeej siv hluav taws xob, thiab tshuab cov cuab yeej siv hluav taws xob, thiab cov cuab yeej siv tsheb.
txoj hluas
TPU muab cov kua muag tsis kam, hnav tsis kam, thiab cov yam ntxwv muaj zog, muaj kub thiab qis thiab kub ua rau cable kev ua tau zoo. Yog li nyob rau hauv Suav lag luam, cov cab ntau xws li tswj cov cable thiab cov khoom siv hluav taws xob siv TPUs los tiv thaiv ntau yam kev tsim qauv.
Cov Khoom Siv Kho Mob
TPU yog kev nyab xeeb, ruaj khov thiab zoo siv cov ntaub ntawv, thiab yuav tsiv mus rau cov tshuaj phthalful, thiab yuav tau tsiv mus rau cov ntshav lossis lwm yam dej hauv lub hnab kho mob los ua rau phiv. Nws tseem yog qhov tshwj xeeb tsim extrusion qib thiab txhaj qib TPU.
daim nyias
TPU zaj duab xis yog zaj duab xis nyias ua los ntawm cov khoom siv tpu los ntawm cov txheej txheem tshwj xeeb xws li dov, casting, thiab txheej. Vim nws lub zog siab, txoj kev tiv thaiv, zoo elasticity, thiab huab cua, khaub ncaws hnav, tshuaj, kev kho mob, thiab lwm thaj chaw.
