Txawm li cas los xij, yog tias qhov no yog koj thawj qhov project ru tsev, nws tuaj yeem ua rau me ntsis tsis meej pem vim muaj ntau cov kauj ruam koom nrog hauv kev txhim kho polycarbonate ru tsev panels. Ua ib qho tseem ceeb tshaj plaws ntawm txhua tus qauv, lub ru tsev yuav tsum raug teeb tsa kom raug thiab ua tau zoo thiab tiv thaiv txhua yam hauv lub sijhawm ntev.
Tias' yog vim li cas kuv thiaj tsim phau ntawv qhia no. Nyeem rau kom paub ntau ntxiv txog tag nrho cov kauj ruam tseem ceeb, nrog rau cov lus piav qhia ntawm cov cuab yeej thiab cov cuab yeej koj xav tau. Yog tias koj xav txhim kho polycarbonate ru tsev panels ntawm yuav luag txhua tus qauv, cov kauj ruam no zoo ib yam, tab sis qee cov kauj ruam yuav txawv ntawm qhov project mus rau qhov project.
1. Txhim kho qhov sib txawv ntawm cov ntsia hlau kom zoo raws li daim ntawv tuab, thiab tsis txhob muaj qhov sib txawv loj lossis me dhau; daim ntawv polycarbonate tej zaum yuav puas los ntawm kev ntxhov siab uas tshwm sim los ntawm qhov sib txawv ntawm cov ntsia hlau me me; daim ntawv polycarbonate tej zaum yuav ruaj tsis khov vim qhov sib txawv ntawm cov ntsia hlau loj heev. Yog li pom zoo kom cov ntsia hlau sib nrug hauv qab no:
A: Polycarbonate ntawv thickness< 3.0="" hli,="" qhov="" sib="" nrug="" ntawm="" qhov="" ntsia="" hlau="" yog="" li="">
B: Cov ntawv polycarbonate thickness> 3.0 hli, cov ntsia hlau sib nrug yog li 30-40cm;
C: Thaum daim ntawv polycarbonate raug kho nrog cov hlua, qhov sib nrug yog li 30cm;
Lus Cim: Yog tias daim ntawv polycarbonate raug kho nrog tus kheej tapping ntsia hlau ncaj qha, nws yog qhov zoo dua los xaiv qhov sib txawv ntawm cov ntsia hlau loj dua.
2. Qhov loj ntawm lub qhov taub yuav tsum xav txog cov ntawv polycarbonate thermal expansion thiab contraction nrog lub caij sib txawv (lub caij ntuj sov los yog lub caij ntuj no) thiab diurnal yam. Feem ntau, qhov loj ntawm lub qhov taub yuav tsum loj dua lub taub hau ntswj 2 ~ 4 hli, kom khaws qhov chaw rau kev nthuav dav. Vim hais tias txoj kab uas hla ntawm cov ntsia hlau yuav tsum yog 2 ~ 4 hli loj dua li txoj kab uas hla ntawm cov ntsia hlau, aluminium spacers yuav tsum tau kho.
3. Lub qhov ntsia hlau yog ze rau ntawm ntug ntawm daim ntawv polycarbonate, uas yooj yim ua rau daim ntawv tawg. Feem ntau, cov ntsia hlau qhov los ntawm ntug ntawm daim ntawv PC yog ntau tshaj 2.5 npaug ntawm txoj kab uas hla ntawm cov ntsia hlau qhov. Xws li qhov chaw ntawm 4 hli txoj kab uas hla screws, cov ntsia hlau qhov yuav tsum yog tsawg kawg yog 5cm ntawm ntug ntawm daim ntawv PC.
4. Tsis txhob xauv cov ntsia hlau nruj heev, txwv tsis pub, ua rau daim ntawv deform thiab ua rau muaj kev ntxhov siab.
5. Nco ntsoov tsis txhob siv rub rivets los kho cov ntawv PC, txwv tsis pub, nws yuav ua rau muaj kev ntxhov siab. Thiab kev ntxhov siab nce nrog daim ntawv thickness nce.
6. Txhawm rau txo cov ntsia hlau siab ntawm daim ntawv, lub tshuab ntxhua khaub ncaws muaj, tab sis PVC gaskets thiab qee lub nplhaib roj hmab yuav rhuav tshem PC panels, uas siv tsis tau. Nws raug pom zoo tias cov khoom siv sab hauv ntawm lub gasket yog EPDM roj hmab aluminium gasket.
7. Cov tshuaj alkaline tsis siv tau, uas tuaj yeem cuam tshuam cov ntawv polycarbonate. Txhua yam khoom uas tuaj yeem ua rau polycarbonate dissolved lossis o yog txwv tsis pub, xws li esters, ketones, halogenated hydrocarbons.
