Muaj qhov tshwm sim zoo li no hauv kev lag luam pob zeb: lub thickness ntawm cov slabs loj tau txais thinner thiab thinner, los ntawm 20mm tuab nyob rau hauv 1990s mus rau 15mm tam sim no, los yog txawm nyias li 12 hli.
Ntau tus neeg xav tias lub thickness ntawm lub rooj tsavxwm tsis cuam tshuam rau qhov zoo ntawm lub pob zeb.
Yog li ntawd, thaum xaiv ib daim ntawv, daim ntawv thickness tsis teem raws li ib tug lim mob.
Raws li cov khoom lag luam, pob zeb slabs tau muab faib ua cov pa slabs, nyias slabs, ultra-thin slabs thiab tuab slabs.
Pob zeb thickness classification
Lub rooj tsav xwm tsis tu ncua: 20mm tuab
Nyias phaj: 10mm-15mm tuab
Ultra-thin phaj: <8mm tuab (rau cov tsev uas yuav tsum tau txo qhov hnyav, lossis thaum txuag cov ntaub ntawv)
Thick Plate: Phaj tuab dua 20mm (rau cov plag tsev nyuaj lossis phab ntsa sab nrauv)
Tshwj xeeb, cov tub lag luam zeb nrog cov ntaub ntawv zoo thiab cov nqi kim yog txaus siab ua kom lub thickness ntawm cov slab thinner.
Vim tias lub pob zeb ua kom tuab heev, tus nqi ntawm cov slabs loj tuaj, thiab cov neeg siv khoom xav tias tus nqi siab dhau thaum xaiv.
Thiab ua kom lub thickness ntawm lub rooj tsavxwm loj thinner tuaj yeem daws qhov kev tsis sib haum xeeb no, thiab ob tog txaus siab.
Disadvantages ntawm nyias pob zeb thickness
① Yooj yim tawg
Ntau lub ntuj marbles yog tag nrho ntawm cov kab nrib pleb.Cov phaj nrog lub thickness ntawm 20 hli yog yooj yim tawg thiab puas, tsis hais cov phaj nrog ib tug tuab ntawm tsawg tshaj li 20 hli.
Yog li ntawd: qhov pom tseeb tshaj plaws ntawm qhov tsis txaus ntawm lub phaj yog tias lub phaj tau yooj yim tawg thiab puas.
② Kab mob tuaj yeem tshwm sim
Yog tias lub rooj tsavxwm nyias dhau lawm, nws yuav ua rau cov xim ntawm cov cement thiab lwm cov nplaum rov qab osmosis thiab cuam tshuam rau cov tsos.
Qhov tshwm sim no yog pom tseeb tshaj plaws rau pob zeb dawb, pob zeb nrog jade kev ntxhib los mos thiab lwm lub teeb xim pob zeb.
Cov phaj nyias nyias yog qhov ua rau muaj kab mob ntau dua li cov phaj tuab: yooj yim rau deform, warp, thiab hollow.
③ Muaj kev cuam tshuam rau lub neej ua haujlwm
Vim nws qhov tshwj xeeb, pob zeb tuaj yeem polished thiab kho dua tshiab tom qab siv lub sijhawm kom nws ci dua.
Thaum lub sij hawm sib tsoo thiab kho dua tshiab, lub pob zeb yuav tsum hnav rau qee qhov, thiab lub pob zeb uas nyias dhau yuav ua rau muaj kev pheej hmoo zoo nyob rau lub sijhawm.
④ Lub peev xwm nqa tsis zoo
Lub thickness ntawm granite siv nyob rau hauv lub renovation ntawm lub square yog 100 hli.Xav tias muaj ntau tus neeg nyob rau hauv lub xwmfab thiab cov tsheb hnyav yuav tsum dhau los, kev siv cov pob zeb tuab zoo li no muaj lub peev xwm loj thiab yuav tsis raug puas tsuaj nyob rau hauv qhov hnyav.
Yog li ntawd, lub thicker lub phaj, qhov muaj zog ntawm qhov cuam tshuam tsis kam;ntawm qhov tsis sib xws, lub phaj nyias nyias, qhov tsis muaj zog ntawm qhov cuam tshuam.
⑤ Kev ruaj ntseg tsis zoo
Dimensional stability yog hais txog cov khoom ntawm cov khoom siv uas nws qhov ntev sab nraud tsis hloov raws li qhov kev txiav txim ntawm txhua yam quab yuam, cua sov lossis lwm yam kev mob sab nraud.
Dimensional stability yog ib qho tseem ceeb tshaj plaws kev ntsuas ntsuas los ntsuas qhov zoo ntawm cov khoom pob zeb.
