TPR muaj qhov zoo hauv qab no: (1) Nws tuaj yeem ua tiav los ntawm cov tshuab thermoplastic molding, xws li kev txhaj tshuaj molding, extrusion molding, tshuab moulding, compression molding, thiab pwm hloov molding;(2) Nws tuaj yeem ua vulcanized nrog roj hmab txhaj tshuaj molding tshuab, thiab lub sij hawm luv luv ntawm li 20min mus rau tsawg dua 1min;(3) Nws tuaj yeem raug molded thiab vulcanized los ntawm ib tug xovxwm, nrog ceev ceev ceev thiab luv vulcanization lub sij hawm;(4) Cov khoom pov tseg tsim tawm hauv cov txheej txheem tsim khoom (tsim tawm burrs thiab extruding khib nyiab roj hmab) thiab cov khoom pov tseg zaum kawg tuaj yeem ncaj qha rov qab siv dua: (5) Cov khoom siv TPR qub tuaj yeem siv tau yooj yim thiab rov siv dua los txo cov pa phem ib puag ncig thiab nthuav dav. lub hauv paus ntawm resource regeneration;(6) Tsis tas yuav vulcanization kom txuag hluav taws xob.Siv lub zog siv hluav taws xob siab siab hose ntau lawm ua piv txwv: 188MJ / kg rau roj hmab thiab 144MJ / kg rau TPR, uas tuaj yeem txuag tau ntau dua 25% ntawm lub zog;(7) Qhov kev txhawb nqa tus kheej yog qhov zoo, thiab cov qauv tsim tau yooj yim heev, kom lub zog ntawm tus neeg sawv cev ntawm cov polymer txo qis heev, thiab kev ua tau zoo yog yooj yim dua rau tus tswv;(8) Nws qhib txoj hauv kev tshiab rau kev lag luam roj hmab thiab nthuav dav daim ntawv thov ntawm cov khoom siv roj hmab.Qhov tsis zoo yog tias qhov kub tsis kam ntawm TPR tsis zoo li cov roj hmab, thiab cov cuab yeej ntawm lub cev poob qis heev nrog qhov kub thiab txias, yog li qhov kev thov ntawm cov ntawv thov raug txwv.Nyob rau tib lub sijhawm, compression deformation, resilience thiab durability yog qis dua cov roj hmab, thiab tus nqi feem ntau siab dua li cov roj hmab zoo sib xws.Txawm li cas los xij, feem ntau, qhov zoo ntawm TPR tseem yog qhov zoo tshaj plaws, thaum cov kev tsis zoo tau txhim kho tas li.Raws li hom tshiab ntawm kev txuag hluav taws xob thiab ib puag ncig-phooj ywg roj hmab raw khoom, TPR muaj kev cia siab rau kev loj hlob.
Polyurethane (PU), lub npe tag nrho yog polyurethane, yog polymer compound.Nws tau tsim los ntawm Otto Bayer hauv xyoo 1937.Polyurethane tau muab faib ua ob pawg: hom polyester thiab hom polyether.Lawv tuaj yeem ua rau hauv cov yas polyurethane (feem ntau yog foamed plastics), polyurethane fibers (hu ua spandex hauv Suav teb), polyurethane rubbers thiab elastomers.
Mos polyurethane feem ntau yog cov thermoplastic linear qauv, uas muaj kev ruaj ntseg zoo dua, tshuaj tiv thaiv, resilience thiab mechanical zog dua li PVC ua npuas ncauj cov ntaub ntawv, thiab muaj tsawg compression deformation.Nws muaj cov thermal rwb thaiv tsev zoo, lub suab rwb thaiv tsev, kev poob siab thiab kev ua haujlwm tiv thaiv kab mob.Yog li ntawd, nws yog siv los ua ntim, suab rwb thaiv tsev, lim khoom.
Rigid polyurethane yas yog lub teeb nyob rau hauv qhov hnyav, zoo heev nyob rau hauv lub suab rwb thaiv tsev thiab thermal rwb thaiv tsev, tshuaj tsis kam, zoo hluav taws xob zog, yooj yim ua, thiab tsis tshua muaj dej nqus.Nws yog tsuas yog siv nyob rau hauv kev tsim kho, tsheb, aviation kev lag luam, thermal rwb thaiv tsev cov ntaub ntawv.
Kev ua haujlwm ntawm polyurethane elastomer yog nruab nrab ntawm cov yas thiab roj hmab, roj ua haujlwm, hnav tsis kam, tsis kub tsis kam, kev laus ua haujlwm, siab hardness thiab elasticity.Feem ntau siv hauv kev lag luam khau thiab kev kho mob kev lag luam.Polyurethane kuj tseem siv tau los ua cov nplaum, txheej, tawv hluavtaws, thiab lwm yam.
Polyurethane tau tshwm sim hauv xyoo 1930.Tom qab ze li ntawm 80 xyoo ntawm kev txhim kho thev naus laus zis, cov khoom siv no tau siv dav hauv cov khoom siv hauv tsev, kev tsim kho, cov khoom siv niaj hnub, kev thauj mus los, thiab cov khoom siv hauv tsev.
Qhov zoo: Rigid PVC yog ib qho ntawm cov khoom siv dav siv ntau tshaj plaws.Cov khoom siv PVC yog cov khoom siv tsis muaj crystalline.
Hauv kev siv tiag tiag, cov ntaub ntawv PVC feem ntau ntxiv nrog cov stabilizers, lubricants, auxiliary processing agents, pigments, impact agents and other additives.
Cov khoom siv PVC tsis muaj nplaim taws, siab zog, huab cua tsis kam thiab zoo heev geometric stability.
PVC muaj zog tiv thaiv oxidants, txo cov neeg ua haujlwm thiab muaj zog acids.Txawm li cas los xij, nws tuaj yeem corroded los ntawm cov concentrated oxidizing acids, xws li concentrated sulfuric acid thiab concentrated nitric acid, thiab tsis haum rau kev sib cuag nrog cov ntxhiab hydrocarbons thiab chlorinated hydrocarbons.
Qhov tsis zoo: Cov yam ntxwv ntws ntawm PVC yog qhov tsis zoo, thiab nws cov txheej txheem yog nqaim heev.Tshwj xeeb, cov ntaub ntawv PVC nrog qhov hnyav molecular hnyav dua yog qhov nyuaj rau kev ua haujlwm (cov ntaub ntawv no feem ntau yuav tsum tau ntxiv cov roj nplua nyeem los txhim kho cov yam ntxwv ntws), yog li cov ntaub ntawv PVC uas muaj qhov hnyav molecular feem ntau yog siv.
Lub shrinkage ntawm PVC yog tsawg heev, feem ntau 0, 2 - 0, 6%.
PVC yog ib qho yooj yim los tso cov pa roj hauv cov txheej txheem molding.
Nylon Advantage:
1. High mechanical zog, zoo toughness, siab tensile thiab compressive zog.Lub zog tensile tshwj xeeb yog siab dua li ntawm cov hlau, thiab lub zog tshwj xeeb compressive yog piv rau cov hlau, tab sis nws cov rigidity tsawg dua cov hlau.Lub zog tensile yog ze rau lub zog tawm los, ntau dua ob zaug siab li ABS.Lub peev xwm nqus ntawm kev cuam tshuam thiab kev ntxhov siab vibration yog muaj zog, thiab qhov cuam tshuam lub zog yog ntau dua li ntawm cov yas zoo tib yam, thiab zoo dua li ntawm acetal resin.
2. Kev qaug zog ua haujlwm yog qhov zoo heev, thiab cov khoom tseem tuaj yeem tswj tau lub zog qub qub tom qab rov kho dua.PA feem ntau yog siv nyob rau hauv cov xwm txheej uas lub sij hawm qaug zog tshwm sim ntawm cov escalator handrails thiab tshiab yas tsheb kauj vab rims yog pom tseeb heev.
3. High softening point thiab kub ua hauj (xws li nylon 46, siab crystalline nylon muaj ib tug siab thermal deformation kub, uas yuav siv tau rau ib ntev lub sij hawm nyob rau hauv 150 ℃. Tom qab iav fiber reinforcement, PA66 muaj ib tug thermal deformation kub ntawm ntau tshaj. 250 ℃).
4. Smooth nto, me me kev sib txhuam coefficient, hnav-resistant.Nws yog tus kheej-lubricating thiab muaj suab nrov tsawg thaum nws yog siv los ua cov khoom siv kho tshuab txav tau.Nws tuaj yeem siv yam tsis muaj roj nplua nyeem thaum muaj kev sib txhuam tsis zoo;Yog tias cov roj nplua nyeem xav tau tiag tiag los txo kev sib txhuam los yog pab cov cua sov dissipation, dej, roj, roj, thiab lwm yam tuaj yeem xaiv.Yog li ntawd, raws li cov khoom sib kis, nws muaj lub neej ua haujlwm ntev.
5. Nws yog resistant rau corrosion, alkali thiab feem ntau ntsev kua, tsis muaj zog acid, cav roj, roj av, aromatic hydrocarbon tebchaw thiab dav cov kuab tshuaj, inert rau aromatic tebchaw, tab sis tsis resistant rau muaj zog acids thiab oxidants.Nws tuaj yeem tiv taus qhov yaig ntawm cov roj av, roj, roj, cawv, qaug zog alkali, thiab lwm yam thiab muaj peev xwm tiv thaiv kev laus.Nws tuaj yeem siv los ua cov khoom ntim rau lubricating roj, roj, thiab lwm yam.
Qhov tsis zoo:
1. Kev nqus dej tsis zoo thiab qhov ruaj khov ntawm qhov ntev.
2. Kev ua haujlwm tsis zoo rau qhov kub thiab txias.
3. Cov cuab yeej antistatic tsis zoo.
4. Cov cua sov tsis zoo.
