Cov txheej txheem qhuav ib txwm siv rau cov tawv nqaij silicone suav nrog cov kua nplaum silicone rau hauv cov slurry siv cov kuab tshuaj, txheej rau hauv cov ntawv tso tawm, ziab, lamination, thiab tom qab ntawd tev tawm los tsim cov khoom tawv. Nws lub ntsiab lus yog nyob rau hauv kev siv cov khoom siv hauv paus ntawm cov khoom siv silicone thiab tso siab rau cov tawv hluavtaws tawv ntau lawm.
Txheej txheem cov ntsiab lus thiab cov ntsiab lus tseem ceeb tswj
1. Raw Materials and Formulation: Silicone polymers: High -kub vulcanized silicone rubber (HTV) los yog ntxiv -hom kua silicone roj hmab (LSR) feem ntau yog siv, muab cov khoom zoo heev thiab kub tsis kam. Additives: Cov no muaj xws li crosslinking agents (kom ua tiav curing), catalysts (xws li platinum catalysts kom ceev cov tshuaj tiv thaiv), ntxiv cov fillers (xws li fumed silica los txhim kho lub zog), colorants (kom faib xim), thiab xav tias cov neeg ua hauj lwm (los kho qhov kev ntxhib los mos). Cov kuab tshuaj: Toluene, xylene, thiab lwm yam, feem ntau yog siv los kho cov slurry viscosity, pab txheej txheej, thiab evaporate tag nrho thaum lub sij hawm ziab.
2. Kev piav qhia ntxaws txog cov txheej txheem tseem ceeb
Txheej: Qhov no yog qhov tseem ceeb hauv kev txiav txim siab qhov kawg ntawm cov tawv nqaij (glossy, matte, textured). Qhov kev ntxhib los mos ntawm daim ntawv tso tawm ncaj qha mus rau ntawm tawv tawv. Cov txheej tuab xav tau kev tswj xyuas meej, feem ntau ntawm 0.1-0.3 hli.
Qhuav/Curing: Qhov no feem ntau ua tiav hauv peb -theem qhov cub:
* Theem 1: Qhov kub thiab txias (piv txwv li, 80-120 degree) tso cai rau feem ntau ntawm cov kuab tshuaj kom evaporate maj mam, tiv thaiv pinholes ntawm qhov chaw.
* Theem 2: Qhov kub nruab nrab (piv txwv li, 130-}160 degree) ntxiv tshem tawm cov kuab tshuaj thiab pib ua ntej kev sib txuas.
* Theem 3: Kub kub (piv txwv li, 170-}200 degree) tso cai rau cov silicone kom tau txais cov tshuaj tiv thaiv crosslinking tag nrho (vulcanization), ua kom ruaj khov peb-dimensional network qauv thiab ua tiav qhov kawg ntawm lub cev.
Laminating: Ib txheej ntawm silicone nplaum yog siv rau cov txheej txheem silicone kho, thiab tom qab ntawd muab khi rau hauv cov ntaub (knitted, woven, lossis non{0}}woven fabric) nyob rau hauv rhuab rollers. Cov kauj ruam no txiav txim siab tag nrho tev lub zog thiab softness ntawm tawv.
Kev kho thiab tev tawm: Cov khoom siv sib xyaw yuav tsum tau muab tso rau hauv chav ntsuas kub tsis tu ncua (xws li 40-60 degree) rau 24-72 teev kom cia cov nplaum txheej kom kho tau zoo thiab ua tiav qhov zoo tshaj plaws adhesion ua ntej nws tuaj yeem rub tawm ntawm daim ntawv tso tawm.
3. Txheej txheem yam ntxwv thiab kev ntsuam xyuas
Qhov zoo: Cov txheej txheem yog qhov paub tab thiab ruaj khov, thiab tuaj yeem hloov kho ncaj qha rau ntawm PVC / PU qhuav - txheej txheem cov kab ntau lawm; cov khoom muaj ib tug mos mos thiab du, thiab lub hauv paus muaj siab thiab tsis kub tsis kam (-60℃rau saum toj no 200 degree), kev laus kuj, thiab non-toxic thiab environmentally friendly khoom ntawm silicone yog zoo heev.
Cov Kev Sib Tw Cov Tub Ntxhais: Cov hnav tsis kam, khawb tsis kam, thiab lub zog siv tshuab ntawm cov xim dawb huv silicon txheej feem ntau tsis zoo rau cov tawv tawv saum - qib PU, uas yog txiav txim los ntawm nws cov qauv molecular. Qhov no kuj yog vim li cas rau txoj kev loj hlob ntawm hybrid qauv technologies xws li LuxSense ™ rau kev txhim kho.
Kev ua kom qhuav ib txwm yog qhov tseem ceeb thiab tseem ceeb ntawm kev tsim cov tawv silicone. Nws zoo kawg nkaus tau txais txiaj ntsig zoo ib puag ncig thiab cov yam ntxwv ntawm cov khoom siv silicone, tab sis nws kuj ntsib qhov kev sib tw ntawm kev ntsuas kev ua tau zoo. Ntawm lawv, qhov kev ua tau zoo ntawm cov ntaub ntawv tseem ceeb LSR / HTV yog lub hauv paus rau kev txhim kho kev ua tau zoo kawg ntawm cov tawv silicone. Txhawm rau kom tus qauv zoo ntawm cov khoom siv tawv silicone, qhia kev lag luam tsim khoom, thiab coj kev lag luam kom tsom mus rau kev txhim kho zoo, pawg txheej txheem "Liquid Silicone Rubber for Silicone Synthetic Leather" tau ua tiav, tsim los ntawm Beijing Guohua Cov Khoom Siv Tshawb Fawb Tshiab Technology thiab coj los ntawm Guangdong Dinglisen New Materials Co., Ltd.
