Ngo-1958, inkampani yaseGecerich Chemical (ngoku i-fufanised lubrizool) ibhaliswe i-TPU Brand Enten okokuqala. Kule minyaka ingama-40 idlulileyo, kuye kwakho amagama angaphezu kwama-20 ojikeleze umhlaba, kwaye uphawu ngalunye lunoluhlu lweemveliso ezininzi. Okwangoku, abavelisi bezinto ezibonakalayo ze-TPU ikakhulu babandakanya i-BOSF, i-Colevestro, i-Lullerizol, iHuntsman Corvic, i-Hunghaa Heng'an, i-shanghaa, i-jachua, i-chauchua, i-chauchua, i-jachua, i-chauchua, i-jachua, i-chauchua, i-jachua, i-chauchua, i-jachua, i-jachua, i-chauchua, i-chauchua, i-chauchua, i-chauchua, i-jachua, i-chauchua, i-chauchua, i-chauchua, i-chauchua, i-jachua, i-chauchua, i-chauchua, i-chauchua, i-chauchua, iXuchi.
1, Udidi lwe-TPU
Ngokwesakhiwo esithambileyo sesahlulo, sinokwahlulwa kuhlobo lwe-polyester, uhlobo lwePolyeether, kunye nohlobo lwe-butadiene, enamaqela anentlonelo, iqela le-ERE, okanye iqela le-ERE, okanye iqela le-ERE.
Ngokwendlela enzima yesahluko, inokwahlulwa ibe luhlobo lwe-urethane kunye nohlobo lwe-urethane urea, efumaneka ngokulandelelana kwi-Ethylene Glycone Chain Ukwahlulahlulwahlulwahlulwahlulwahlulwahlulwa kwahlulwahlulwahlulwa ngohlobo lwePolyester kunye nohlobo lwePolyet.
Ngokutsho kobukho okanye ukungabikho komnqamlezo onqamlezileyo, kunokwahlulwa kwi-thermoplastic ecocekileyo kunye ne-semi thermoplastic.
Okwangaphambili unesakhiwo esisulungekileyo se-gener kwaye akukho ntambo-hluma intambo; Le yokugqibela iqulethe inani elincinci leBonds enxulumene ne-Allofphanininininininininininininininininininininininininininininininininininininininininininininininininininininininininininininininininininic.
Ngokutsho kokusetyenziswa kweemveliso ezigqityiweyo, zinokwahlulwa zangamacandelo aphezulu (into eyohlukeneyo yoomatshini), imibhobho (i-sheings, iifilimu (iifilimu, iipleyiti ezincinci), iipleyiti, iifayili, njl.
I-2, Synthesis ye-TPU
I-TPU ye-polyurethane malunga nemo yemolekyuli. Ke, kwenzeka njani?
Ngokwenkqubo ye-Synthesi eyahlukeneyo, ihluleke ikakhulu ukuba ibe yi-bulfmerizazation kunye nesisombululo se-polymerization.
Ngokobuninzi bePolymerization, inokwahlulwa kwiNdlela yePolymermerazazazazazazozarazazazozarazazazazazazozarazazazozarazazazazazazation kunye nendlela yenyathelo elinye ngokusekwe kubukho okanye ukungabikho kokuphendula kwangaphambili:
Indlela yokwenziwa kwangaphambili ibandakanya uthatha u-Diisoclocloncnaenate nge-macromoralecular diols ixesha elithile ngaphambi kokufaka ulwandiso lwe-TPU;
Indlela yenqanaba elinye ibandakanya ukudibanisa kwangaxeshanye kwaye isebenze nge-fiomolecular diols, diocysates, kunye ne-chain badlulise i-TPU.
Isisombululo sePolymerization ibandakanya ukuguqula isinyithisileyo kwi-Solvent, emva koko ukongeza i-fiomolecular diols ukuba iphendule ixesha elithile, kwaye ekugqibeleni yongeza i-TPU.
Uhlobo lwecandelo le-TPU, i-molecular isisindo, umxholo we-hard okanye othambileyo, kunye ne-TPU Remoremere Retiment can ichaphazela ukuxinana kwe-TPU, kunye nokuxinana kwe-1,10-125, kwaye akukho mahluko ubalulekileyo xa kuthelekiswa nezinye iirubres kunye neplastiki.
Ebunzima obufanayo, ukuxinana kwePolyber Tect TPU iphantsi kuneso sohlobo lwePolyester TPU.
I-3, ukulungisa i-TPU
Amasuntswana e-TPU afuna iinkqubo ezahlukeneyo zokwenza imveliso yokugqibela, ikakhulu kusetyenziswa iindlela zokunyibilika kunye nezisombululo zokulungisa i-TPU.
Ukunyibilikisa inyibilikisi yinkqubo esetyenziswayo kwishishini leplastiki, njengokuxuba, ukuqengqeleka, ukupheliswa, ukubetha, nokubumba;
Ukuqhutywa kwesisombululo yinkqubo yokulungiselela isisombululo ngokunyibilikisa amasuntswana kwi-solvent okanye ngokuthe ngqo kwi-polymermenti yokunyibilikisa, emva koko aqengqele, njalo njalo.
Imveliso yokugqibela eyenziwe kwi-TPU ngokubanzi ayifuni ukulungisa okungaqhelekanga, nto leyo enokuthi icofe umjikelo wemveliso kunye nezixhobo zenkunkuma.
I-4, ukusebenza kwe-TPU
I-TPU inomomongo ophezulu, amandla aphezulu, i-eloutyus ephezulu kunye ne-elastice, ichaphazele ngokuchasene neoyile, ukumelana kweoyile, ukumelana nobushushu obuphantsi, kunye nokuxhathisa gadalala.
Amandla amakhulu e-sunsengation, i-Eloutyhation ephezulu, kunye ne-Loctoration Apperation yexesha elide yexesha elide zonke izibonelelo ezibalulekileyo ze-TPU.
IXiaou iya kucacisa ikakhulu kwiipropathi zoomatshini ze-TPU ezivela kwimiba efana namandla e-thensile kunye ne-Elongwation, ulondolozo, njl.
Amandla aphezulu e-thensle kunye ne-Elongwation ephezulu
I-TPU inamandla obunye kunye ne-elongwation. Kwidatha esezantsi le mifanekiso ingezantsi, siyabona ukuba amandla e-subile kunye ne-elongwetion ye-POLETEETER Chwethe i-TPU ilunge ngakumbi kunezo zeplastiki zePilyvinyl iplasitiki kunye nerabha.
Ukongeza, i-TPU inokuhlangabezana neemfuno zomzi-mveliso wokutya kunye nongezilonge zongezwa ngexesha lokuqhubekiswa, okunzima kwezinye izinto ezinjenge-PVC kunye nerabha ukuze zifezekise.
Ukomelela kunomdla kakhulu kubushushu
Ukomelela kwe-TPU kubhekiselelwe kwinqanaba apho kuya kuphinda kutshanjelwe imeko yayo yoqobo emva kokuba uxinzelelo lokusebenza likhululwe, elingumyinge wokubuyisela kwimeko yesiqhelo emsebenzini ofunekayo ukuvelisa impatho. Kungumsebenzi wemodyuli eguqukayo kunye nengqumbo yangaphakathi yomzimba we-elastiki kwaye inovelwano kakhulu kubushushu.
Ukuphinda kuphendule kuyancipha ngokuncipha kweqondo lobushushu kude kube kubushushu obuthile, kwaye ubushushu obuqhelekileyo buyanyuka ngokukhawuleza. Eli qondo lobushushu liqondo lokushisa elithambileyo lecandelo elithambileyo, eligqitywe sisimo se-macromolecular diol. Uhlobo lwePolyet Tet i-TPU isezantsi kune-Polyster Chwetherti. Kwiqondo lobushushu elingaphantsi kobushushu bekristali, i-elastomer iba nzima kakhulu kwaye iphulukane ne-elasticy. Ke ngoko, ukomelela kuyafana nokuphindaphinda kumphezulu wesinyithi.
Ubunzima be-Hardy i-shore A60-D80
Ubunzima sisibonisi sokukwazi kwezixhobo zokumelana nengxaki, ukufaka amanqaku, kunye nokukrala.
Ubulukhuni be-TPU buhlala buyilinganisa usebenzisa i-shore a kunye nonxweme lwe-Dards, ngonxweme olusetyenziselwa ukuthambisa i-TPUS kunye nonxweme d esetyenziselwa ubunzima be-TPU.
Ubulukhuni be-TPU bunokuhlengahlengiswa ngokuhlengahlengiswa kwenani lamacandelo athambileyo kunye namandla. Ke ngoko, i-TPU inobuqili ngokubanzi, ukusukela elunxwemeni A60-D80, ukususela kubunzima berabha kunye neplastiki, kwaye kunexesha eliphakamileyo kakhulu.
Njengoko ubunzima obutshintsha, ezinye iipropathi ze-TPU zinokutshintsha. Umzekelo, ukwandisa ubulukhuni be-TPU kuya kukhokelela kutshintsho lwentsebenzo olunjengokunyusa i-tensles modyuli kunye noxinzelelo lwentengisim, ukuncipha komgangatho (ukwanda kokungavisisani kokusingqongileyo kunye nokwanda kokumelana nokusingqongileyo.
5, Ukusetyenziswa kwe-TPU
Njengomntu obalaseleyo we-elastomer, i-TPU inoluhlu olubanzi lwezikhombisi zemveliso kwaye zisetyenziswa kakhulu kwiimfuno zemihla ngemihla, iimpahla zezemidlalo, iimpahla zezemidlalo, izixhobo zokuhombisa, izixhobo zokuhombisa, kunye nezinye izinto.
Izixhobo zeShie
I-TPU isetyenziselwa ikakhulu izinto zesihlangu ngenxa yokungaqondakali kunye nokunganyangeki. Iimveliso zeenyawo eziqukethe kakhulu i-TPU zikhululekile kakhulu ukuba zinxibe iimveliso zezihlangu rhoqo, ke zisetyenziswa ngokubanzi kwiimveliso eziziintsizi eziphezulu, ngakumbi izihlangu ezithile kunye nezihlangu eziqhelekileyo.
hose
Ngenxa yokuthamba kwayo, amandla amanye amanye amanxuwa, amandla empembelelo, kunye nokuxhathisa amaqondo obushushu aphezulu, amajuba e-TPU asetyenziswe ngokubanzi e-China njengeenqwelo moya, iitanki, izithuthi, kunye nezixhobo zomatshini.
intambo
I-TPU ibonelela ngokuchasene ne-TAR, inxibe ukunganyangeki, kunye nokugoba iimpawu, kunye nokuchasana nobushushu obuphakathi kunye nokuphantsi kweqondo lobushushu nokuba sisitshixo sokusebenza kwentambo. Ke kwimarike yaseTshayina, iintambo eziphezulu ezifana neentambo zolawulo kunye neentambo zamandla zisebenzisa i-TPU ukukhusela izixhobo zokuzila okuntsonkothileyo, kwaye izicelo zazo ziya kusinda ngakumbi.
Izixhobo zonyango
I-TPU yindawo ekhuselekileyo, enesitali neyona iphambili ye-PVC, engayi kuba ne-Phthalate kunye nezinye izinto eziyingozi zekheminyi, kwaye ziya kutyeshela igazi okanye ezinye izinto zotywala ezikumnyango wezonyango okanye ibhegi yezonyango ukuba ibangele iziphumo ebezingalindelekanga. Ikwalibanga lokuphumelela kwibanga lokuphumelela kunye nenaliti.
ifilimu
Ifilimu ye-TPU yifilimu ecekeceke eyenziwe kwi-TPU Granular isebenzisa izixhobo ze-TPU ngeenkqubo ezizodwa ezinjengokuqengqeleka, ukuvuthuza, kunye nokuthuka. Ngenxa yamandla ayo aphakamileyo, nxiba ukunganyangeki, ukuqina okuhle, kunye nokuxhathisa kwemozulu, izixhobo ze-TPU zisetyenziswa ngokubanzi kumashishini, izixhobo ze-TPU, izixhobo ze-SHE, iZinyithi, kwi-imeyile, ezonyango, kunye nezinye iiNdawo.
