Cov khoom siv rov ua dua tshiab hauv cov yas pallets yog qhov loj me thiab tsis muaj cov ntawv xov xwm

Cov ntaub ntawv ntawm cov yas pallets tuaj yeem muab faib ua cov khoom siv tshiab (feem ntau hu ua raw khoom) thiab cov khoom siv rov ua dua tshiab (feem ntau hu ua clinker). Cov khoom lag luam tshiab muaj kev ua tau zoo dua li cov khoom siv rov ua dua tshiab, thiab tus nqi yog qhov tseeb siab dua li cov khoom siv zoo tib yam. Qhov kev faib ua feem ntawm cov khoom siv rov ua dua tseem cuam tshuam ncaj qha rau tus nqi ntawm cov yas pallets.

Cov khoom siv rov ua dua tshiab yog ib lub sij hawm txhaj tshuaj molded tais nrog ib feem ntawm cov khoom siv rov ua dua tshiab. Nws yog qhov pom tseeb tias qhov ntau ntawm cov khoom siv rov ua dua tshiab, tus nqi qis dua thiab tus nqi qis dua.

Los ntawm cov tsos, cov yas rov ua dua tshiab muaj qhov tsis zoo, qhov saum npoo ntawm cov khoom yog npub, qhov loj me tsis sib xws, muaj impurities, thiab lawv feem ntau yog xim lossis grey; thaum cov khoom tshiab muaj qhov zoo gloss, qhov saum npoo ntawm cov khoom yog du, qhov loj me yog uniform, thiab nws tsis muaj cov ntawv xov xwm. Nws yog xim tsis muaj xim los yog mis nyuj dawb. Cov khoom tshiab yog xim ci thiab cov khoom qub yog xim daj. Tsis tas li ntawd, yog tias peb xav paub qhov txawv kom zoo, peb tuaj yeem paub qhov txawv ntawm 7 yam hauv qab no:

1. Xim: cov pob tshab zoo dua li cov opaque, txawm tias cov xim zoo li cas.

2. Gloss: Zoo gloss zoo dua tsis muaj gloss, uas yog xim ntawm cov khoom nto.

Hais txog lub cev thiab cov khoom siv kho tshuab, cov khoom siv rov ua dua yog tsim los ntawm cov khoom pov tseg. Tom qab cua thiab hnub ci, qhov saum npoo ntawm cov yas tau degraded thiab degraded. Nws tau yaj thiab plasticized los ntawm ntau qhov kev ua haujlwm kub. Nyob rau hauv qhov kev txiav txim ntawm lub teeb, oxygen thiab kub kub, ib feem ntawm cov polymer Tom qab oxidized, macromolecular saw yuav tawg thiab degraded, uas yuav txo tau lub cev thiab txhua yam khoom.

3. Hlau kos duab: Tom qab tshuab hluav taws xob tawm, sai sai kov cov yaj nrog ib qho khoom siv hlau, thiab tom qab ntawd rub tawm sai sai kom pom tias cov hlau zoo li qub. Yog hais tias nws yog uniform, nws yog cov khoom zoo. Tom qab rub ob peb zaug, sib tshooj ntawm cov hlau, rub nws rov qab los saib seb nws puas muaj elasticity, thiab seb nws puas tuaj yeem rub tawm dua thiab tsis tu ncua. Nws yog qhov zoo uas nws tsis tawg lossis tawg tom qab ib qho kev ncua deb.

4. Ignite (xyuas seb cov xim ntawm cov nplaim hluav taws muaj pa taws, puas muaj hluav taws kub hnyiab los yog tsis kub);

5. Cov ntxhiab tsw ntxhiab (ntau yam ntxhiab tsw ntxhiab tsw txawv, nrog rau cov nplaim hluav taws, thiab lwm yam);

6. Yog hais tias qhov saum toj no tsis tuaj yeem lees paub, thov siv hluav taws kub dua. Thaum lub sij hawm hlawv, cov pa luam yeeb dub yuav tawm los yog cov yaj yuav poob sai sai, uas tsis zoo.

7. Floating dej: Tsuav yog muaj dej submerged, nws yog phem. Yog hais tias qhov saum toj no tseem tsis paub meej lossis tsis tau txiav txim siab, tsuas muaj lub tshuab kuaj.
