Vim li cas Silicone Roj Hmab muab faib ua A thiab B

Vim li cas cov roj hmab silicone muab faib ua A thiab B?

Silicone A thiab B sib xyaw feem ntau yog hais txog kev sib xyaw ntawm ob-cov khoom (los yog ob-kua) silicone. Cov txheej txheem silicone no muaj ob qhov tseem ceeb: silicone A (tseem hu ua lub hauv paus lossis cob) thiab silicone B (feem ntau yog tus neeg saib xyuas lossis cov khoom siv hluav taws xob).

Thaum ob qho khoom sib xyaw ua ke hauv ib qho kev faib ua feem, lawv hnov ​​​​mob chemical, ua rau cov silicone kho rau hauv cov duab los yog cov qauv uas xav tau.

Sib tov cov kauj ruam
Kev Npaj: Ua kom thaj chaw ua haujlwm huv si thiab tsis muaj plua plav, thiab npaj cov cuab yeej uas yuav tsum tau ua, xws li nplawm rods, ntsuas khob, sib tov ntim, thiab lwm yam. Tib lub sijhawm, xyuas seb lub ntim ntawm silicone A thiab B puas zoo lawm thiab. paub meej tias lawv lub neej txee.
Kev ntsuas: Raws li qhov piv ntawm cov khoom siv phau ntawv, ntsuas qhov tseeb ntawm silicone A thiab B. Qhov piv no yog qhov tseem ceeb kom tau txais qhov zoo tshaj plaws curing nyhuv thiab kev ua tau zoo.
Kev sib xyaw: Ncuav silicone A rau hauv lub thawv sib xyaw, tom qab ntawd maj mam ntxiv silicone B, thaum nplawm kom huv si nrog ib tus pas nrig nplawm. Tsis txhob ua npuas ntau dhau thaum nplawm thiab xyuas kom meej tias ob qho khoom sib xyaw ua ke. Lub sij hawm stirring yuav txawv ntawm cov khoom mus rau cov khoom, thov ua raws li cov lus pom zoo ntawm cov khoom siv phau ntawv.
Degassing: npuas yuav tsim nyob rau hauv cov khoom sib xyaw silicone, uas yuav cuam tshuam rau cov tsos thiab kev ua tau zoo tom qab kho. Yog li ntawd, ua ntej nchuav cov silicone rau hauv pwm los yog siv rau saum npoo, nws yuav tsum tau degassed. Qhov no tuaj yeem ua tiav los ntawm kev sawv ntsug, lub tshuab nqus tsev degassing lossis vibration.
Daim ntawv thov: Ncuav cov degassed silicone rau hauv pwm los yog siv rau hauv txoj hauj lwm uas yuav tsum tau, thiab tom qab ntawd tos kom nws kho. Lub sijhawm kho yog nyob ntawm hom silicone, kub thiab lwm yam, thov mus saib cov lus qhia ntawm cov khoom siv phau ntawv.
Cov kev ceev faj
Thaum sib tov thiab siv silicone, nco ntsoov hnav cov khoom tiv thaiv tus kheej tsim nyog xws li hnab looj tes, tsom iav thiab tiv thaiv ua pa.
Tsis txhob sib cuag ncaj qha ntawm silicone A thiab B thiab tawv nqaij, qhov muag lossis khaub ncaws, vim tias lawv yuav ua rau khaus lossis khaus.
Silicone yuav tso tawm cua sov thaum lub sijhawm kho, yog li xyuas kom ua haujlwm nyob rau hauv qhov chaw zoo-ventilated thiab tsis txhob piling ntau ntawm silicone los tiv thaiv overheating.
Kho silicone yuav nyuaj rau tshem tawm ntawm qee qhov chaw, yog li thov ua tib zoo xav txog qhov twg thiab nws yuav siv li cas ua ntej siv.
