kua rtv-2 silicone rau gypsum khoom molding
Daim ntawv thov kua roj rtv-2 silicone rau gypsum khoom molding
Ricer rtv-2 silicone rau gypsum khoom molding yog mas siv rau cov khoom noj khoom haus gypsum, plaster, cob, cement mould yog zoo rau casting Plasters, Cements thiab cov khoom ua si, khoom ua si khoom siv, khoom plig thiab ntawv sau, cov khoom loj loj, kev sib tw ntawm kev cai relics pwm, thiab lwm yam .
Kev piav qhia ntawm kua rtv-2 silicone rau gypsum khoom molding
kua rtv-2 silicone rau gypsum khoom molding yog ntws kua nrog zoo zoo nyob rau hauv txawm xim. Nws muaj ob yam, qhov kev tivthaiv A yog silicone roj hmab, thiab B tivthaiv kabmob yog tus neeg sawv cev kho lossis tus sawv cev ntawm cov neeg ua haujlwm. Tus txheej txheem ua ntej thiab npaj cov qauv pwm los yog cov khoom yuav tsum tau duplicated, siv ntau npaum li cas ntawm cov roj hmab silicone, ntxiv 2-3% tus neeg sawv cev kho, thiab muab sib tov rau kev siv. Ib khub pwm tuaj yeem ua tau zoo thiab tsim hauv 2-3 teev. Cov pwm tsim tau siv dua los tsis muaj kev sib deev thiab dej ntsws thiab muaj kev kub siab, ua kom muaj kev sib tw ceev nrig ntawm cov khoom nrog cov khoom muag 2. Lub tshuab 618 pwm tuaj yeem yog muaj feem xyuam rau kev tuav cov pwm thiab cov khoom tsawg tsawg.
Ua Haujlwm Kev Qhia ntawm kua roj rtv-2 silicone rau gypsum khoom molding
1. kua rtv-2 silicone rau gypsum khoom molding yog siv rau cov khoom me me los yog cov khoom nrog cov qauv zoo. Cov pwm rau cov nplua thiab cov khoom me me yuav tsum tau ua ntawm cov pob txha mos los tiv thaiv cov khoom ntawm kev txhim kho yooj yim thaum demoulding.
2. Yog tias cov khoom siv loj loj los sis cov khoom sib txuas, cov pwm yuav tsum ua los ntawm txoj hlua hnyav ntawm cov xim uas muaj zog dua kom cov khoom tsim yuav tsis deform.

Cov lus qhia rau kev tsim cov tshuaj Silicone pwm
1. Ua kom tawv nqaij thiab dawb ntawm cov ntaub xoob.
2. Poob 100 Tshooj A hauv qab thiab 2 ntu ntawm CA30 Curing Agent nyob rau hauv ib lub thauv pov tseg.
3. Qia Tshooj A hauv paus silicone ua ntej siv kom huv si, raws li cov sib qui rau kev sib cais yuav tshwm sim thaum muab cov khoom cia ntev.
4. Muab Seem A thiab Tshooj B sib npaug kom txog rau thaum CA30 txav mus rau hauv lub hauv paus.
5. Ncuav qhov mixed Part A lub hauv paus silicone thiab CA-30 tua tus neeg sawv cev sai li sai tau rau qhov qub
6. De-pwm tom qab 24 xuab moos, nws yuav ua kom zoo dua lub sij hawm ntawm cov kua pliav.
Ceebtoom: Nws tau pom zoo kom tso tau cov cua nkag rau hauv lub tshuab nqus tsev, cia cov ntse kom nthuav dav thiab ces rov tawm. Tom qab ntxiv 1-2 mins hauv lub tshuab nqus tsev, yuav tsum tau kuaj xyuas cov khoom siv thiab yuav siv tau yog tias tsis muaj pa npuas. Lub ntim nce ntawm 3-5 zaug yuav tshwm sim ntawm lub tshuab nqus cov pa dej. Li ntawd, yuav tsum xaiv ib lub thawv ntim zoo.
Tsis tshua muaj kua RTV-2 Silicone rau Gypsum Cov Khoom Pwm Tsim
Thaum RTV-2 Silicone Roj Hmab muab cia rau hauv los yog qis dua 30 ° C (85 ° F) hauv cov thawv uas tsis tau qhib, RTV2 Silicone Base thiab CA30 Curing Agent muaj 12 lub hlis ntawm hnub pib. Tom qab 12 lub hlis, thov siv lub nplawv zeb ua cov seem A silicone rau qee feeb, tom qab ntawd lub silicone siv tau dua, tsis muaj cawv rau lwm qhov kev ua tau zoo.
FAQ ntawm RTV-2 Silicone Rubber rau Pwm Tsim
Vim li cas cov RTV kua silicone roj hmab rau molding muaj ob peb pwm ua lub sij hawm?
Silicone rubber pwm muaj ntau lub sij hawm moulding yog vim cov follwoing vim li cas: muab ntau cov roj silicone uas yuav ua kom lub molecular ntawm cov roj hmab silicone; ua cov pwm rau cov khoom me thiab nplua ntxim khoom uas muaj zog dua zeeg roj hmab uas yog yooj yim tawg; ua cov pwm rau cov khoom loj uas muaj cov xim silicone rubber uas yuav txo tau cov tensile thiab rhuav lub zog ntawm cov pwm, thiab cov pwm yuav muaj deformation. Yog li, peb yuav tsum siv cov roj hmab kom zoo uas yog tsim kom muaj cov khoom lag luam uas tsim nyog.
