Tsis yog ib lub rooj tog ntau lawm tuaj yeem ua yam tsis muaj cov nplaum tshwj xeeb uas yuav ua kom muaj kev sib raug zoo ntawm cov khoom thaum sib dhos. Nws yog rau cov hom phiaj no uas kub yaj nplaum nplaum yog siv, uas yog cov khoom granule uas tau txais lub xeev khov thaum rhuab thiab ceev ceev thaum txias.
Composition
Cov khoom ntawm cov khoom no yog muab los ntawm cov khoom tshwj xeeb hauv cov khoom sib xyaw. Feem ntau cov ntaub nplaum nplaum yog tsim los ntawm vinyl acetate thiab ethylene copolymer.
Qhov kev sib xyaw no muab cov khoom lag luam:
- adhesion zog;
- zoo viscosity;
- cohesive zog;
- zoo sib xws nrog lwm cov ntaub ntawv.
Txhawm rau txhawm rau txhim kho cov khoom ntawm cov khoom, cov nplaum kub yaj kuj tseem muaj ntau yam:
- hloov pauv;
- plasticizers;
- Yantioxidants.
Txhua yam no muab cov khoom kawg zoo dua ntub dej, nce elasticity, tsawg shrinkage, qis thermal degradation thiab ntau ntxiv.
Txoj kev xaiv
Yuav kom cov nplaum nplaum kub rau ntawm ntug kom zoo tagnrho, nws yog ib qho tsim nyog yuav tsum coj mus rau hauv tus account tus yam ntxwv ntawm cov ntaub ntawv rauvaj huam sib luag cladding. Yog tias tsuas yog qee yam ntawm cov npoo feem ntau siv rau hauv kev tsim khoom, ces tsuas yog cov nplaum kub yaj uas pom zoo rau cov khoom zoo li no yuav tsum tau siv. Nyob rau hauv rooj plaub ntawm kev siv ntau hom npoo nrog tib zaus, koj yuav tsum xaiv cov nplaum universal uas haum rau txhua yam khoom siv.
Cov neeg siv khoom kuj tseem muaj cov nplaum nplaum uas tsis muaj cov nplaum. Cov tom kawg yog pheej yig dua thiab feem ntau nyiam cov xim, tab sis lawv qhov ceev yog ntau dua, uas txhais tau hais tias kev noj thaum lub sij hawm thov yuav loj. Yog li ntawd, pheej yig tsis ua rau nws tus kheej. Muaj cov xwm txheej thaum cov nplaum zoo li no tseem tsim nyog, txij li lawv sau cov txheej sib sib zog nqus ntawm chipboard zoo.
Design nta
Tsis tas li, thaum xaiv, koj yuav tsum xyuam xim rau cov yam ntxwv ntawm cov kua nplaum nws tus kheej. Cov khoom nkag rau hauv daim ntawv pas nrig tsis tas yuav ua kom tiav melting ua haujlwm. Nws yog siv rau qhov chaw, maj mam yaj los ntawm ib tug ntug, yog li txhim kho qhov zoo ntawm gluing. PVC edging thiab EVA kub yaj nplaum kuj tuaj yeem koom nrog hauv cov qauv sib txawv, feem ntau siv rau cov qauv nyuaj. Qhov kev xaiv no suav nrog kev siv cov kua nplaum hauv lub xeev ua kua rau ntawm ntug, tom qab uas nws raug xa mus rau cov neeg siv khoom. Tsis tas li ntawd, rau cladding, cov nplaum yuav tsum tau rov ua dua nrog cua kub thiab ua ke nrog lwm qhov chaw. Nyob rau tib lub sijhawm, kev ua haujlwm ceev yog qhov tsawg, tab sis kev noj cov kua nplaum kuj tsawg, vim tias txhua yam kev tsis xws luag hauv cov qauv ntawm cov gluing raug tshem tawm.
Txoj Cai Cia Khoom
Thaum ua haujlwm, zammuaj peev xwm tsub zuj zuj ntawm noo noo ntawm qhov chaw thiab cov nplaum, yog li tag nrho cov npoo thiab cov rooj tog zaum tsuas yog muab tso rau hauv kev khiav hauj lwm ncaj qha los ntawm ib tug sov so warehouse. Nyob rau hauv cov ntaub ntawv ntawm lawv lub xeev txias, noo noo condenses ntawm lub txias npoo thiab impairs lub adhesion ntawm qhov chaw rau cov nplaum.
Ua haujlwm kub
Yuav kom cov nplaum kub yaj kom muaj peev xwm muab kev cog lus zoo, koj yuav tsum ua haujlwm nrog nws tsuas yog qee qhov kub. Feem ntau cov chav nyob muaj peev xwm muab tau qhov kev xav tau, tab sis nyob rau hauv tej yam kev mob qhov kub thiab txias yuav txo tau.
Piv txwv li, thaum:
- muaj cov nplaum nplaum nplaum rau hauv lub tank;
- qis nrawm xa khoom rau qhov chaw thov
- ua haujlwm nrog qhov txias.
Nuances of application
txhawm rau xyuas kom pom qhov adhesion, txheej ntawm cov nplaum nplaum yuav tsum yog cov tuab tuab. Cov kua nplaum ntau dhau yuav nyem tawm cov npoo thaum nias, tab sis yuav muab adhesion zoo dua. Ib qho me me ntawm cov muaj pes tsawg leeg yuav tsis ua rau muaj kev sib kis ntawm qhov chaw ua haujlwm, tab sis yuav tsis muaj peev xwm muab qhov kev sib raug zoo ntawm kev sib raug zoo. Tom qab siv cov khoom, cov khoom tam sim ntawd raug xa mus rau lub clamp, uas yog nqa los ntawm cov xovxwm steel nrog cov chais du.
khoom siv niaj hnub
Hnub no, qhov zoo tshaj plaws kub yaj nplaum nplaum rau PVC los ntawm cov ntaub ntawv polyurethane tau txiav txim siab. Qhov kev sib xyaw no tau sau tag nrho cov txiaj ntsig ntawm cov pa thiab cov khoom siv tshuaj tiv thaiv. Polyurethane nplaum muaj peev xwm ua kom tawv tsis tau tsuas yog nyob rau hauv lub cev muaj zog ntawm qhov kub thiab txias, tab sis kuj nyob rau hauv cov tshuaj. Tshwj xeebcov isoacites nyob rau hauv cov nplaum nplaum cross-linked nyob rau hauv lub zog ntawm ya raws, yog li hloov cov muaj pes tsawg leeg mus rau hauv ib tug peb-dimensional bonding qauv.
Ua kom tiav cov khoom zoo li no yuav siv sijhawm ob peb hnub, tab sis txhua yam nyob ntawm lwm yam:
- ntu ntu thiab ib puag ncig;
- ntu thiab qhov ntsuas kub ib puag ncig;
- tshuaj muaj pes tsawg leeg ntawm cov kua nplaum.
Khaws cov nplaum ntawm ib qho kev sib xyaw yuav tsum tau ua nruj me ntsis hauv cov chaw kaw ntom ntom ntawm qhov kub thiab txias, vim tias nyob rau hauv qhov cuam tshuam ntawm cov khoom tsis zoo, cov khoom poob nws cov khoom. Yog hais tias noo noo tau los ntawm cov nplaum, nws yuav siv tsis tau. Thaum cov nplaum tau ua tiav tiav, nws qhov kev tiv thaiv tau pom nyob rau hauv qhov kub ntawm -30 txog +150 degrees.
