Raws li cov niaj hnub ntawm rooj tog uas ua ke ua ke thiab ua yeeb yam, tsim qhob cov khoom kev kawm txuj ci, thiab cov txheej txheem ua kom zoo nkauj. Los ntawm Raw cov khoom xaiv rau cov khoom kawg, txhua kauj ruam yuav tsum tau tswj kom ntseeg tau tias cov khoom siv zog, durability, thiab zoo nkauj.
Kauj ruam 1: Tsim thiab Pwm Ua
Cov rooj qhob qhob pib nrog cov qib tsim. Tus tsim qauv txiav txim siab qhov loj me, cov qauv, thiab tsim cov ntsiab lus ntawm cov ntsiav tshuaj raws siv, xws li kev siv tshuaj, txiav, lossis ua kom zoo nkauj- hauv kev kho kom zoo nkauj. Ib pwm yog tom qab ntawd tsim raws li tus qauv tsim. Cov pwm no feem ntau yog ua los ntawm high- ntom silicone, polyester cob, lossis cov ntsiab lus zoo tom qab kev ua kom pom tseeb. Rau cov duab nyuaj, cov pwm raug tsim hauv cov ntu, thiab cov txheej txheem sib dhos yuav tsum npaj ua.
Kauj ruam 2: Cov khoom siv cov khoom siv sib txuam
Cov khoom siv tseem ceeb ntawm lub rooj ua haujlwm ua vaj tse ua vaj tse, tab sis nws cov qauv yuav tsum tau ua kom zoo rau kev sib npaug lub zog thiab qhov hnyav. Lub hauv paus ntaub ntawv suav nrog cov cement (xws li Portland Maas), kev sib sau ua ke (cov xuab zeb zoo nkauj thiab pob zeb thiab cov roj av roj hmab (xws li dej reducers thiab redarders). Mineral cov pigments los yog fiberglass tuaj yeem ntxiv rau txhim kho cov kev ntxhib los mos thiab tawg. Thaum sib xyaw, cov dej - kev piv txwv yuav tsum raug tswj kom nruj kom tsis txhob muaj shrinkage thiab tawg tshwm sim los ntawm noo noo ntau heev. Neeg kho tshuab sib xyaw tseem siv los xyuas kom ntseeg tau cov kev sib luag.
Kauj ruam 3: nchuav thiab moulding
Qhov npaj ua vaj tse slurry yog hliv rau hauv pwm. Lub rooj vibrating lossis phau ntawv tapping ntawm pwm yog siv los tshem tawm cov npuas huab cua thiab xyuas kom meej. Rau ob {- txheej qauv (xws li cov ntsiav tshuaj thiab txhawb nqa ob txhais ceg), lub sijhawm ua haujlwm tau raug tswj hwm kom ntseeg tau tias ib qho kev sib raug zoo. Tom qab molding, cov qhob yog them nrog cov ntawv yas lossis daim ntaub ntub dej rau kev kho, tswj cov av noo los txhawb kev ua kom dej xis. Lub voj voog uas tab tom yog feem ntau 7-14 hnub.
Kauj Ruam 4: Txhib thiab tshaj tawm - kev ua
Thaum cov qhob tau mus txog qhov muaj zog txaus, nws yog cov dab neeg thiab saum npoo tsis zoo yog tshuaj xyuas thiab kho. Qhov thaiv kev ntxhib yuav tsum sib tsoo, polishing, lossis pickling kom ua tiav ntau yam textures, xws li matte, lossis tshuaj antumed. Cov npoo yuav tsum tau ua chamfering rau kev nyab xeeb ntau ntxiv, thiab yuav tsum muab xov zoo rau kev txhim kho kom muaj kev tiv thaiv dej. Thaum kawg, hlau nkhaus yuav tsum tau nruab lossis cov qauv kev txhawb nqa tau hloov kho kom ntseeg tau tias muaj kev ruaj ntseg tag nrho.
Lub tsev ua vaj tse cov lus ua kom zoo nkauj ntawm cov ntaub ntawv fusion ntawm cov ntaub ntawv tsoos thiab cov qauv niaj hnub, nrog txhua txhua yam kev nthuav dav ncaj qha cuam tshuam. Qhov kev ua tau zoo no ua rau hauv ib qho ntawm rooj tog uas yog ob qho tib si churable thiab kos duab muaj txiaj ntsig.
