Kub yaj nplaum: lub ntsiab yam ntxwv ntawm

Tsis muaj leej twg lub rooj tog ntau lawm yog tsis muaj peev xwm ua tsis muaj tshwj xeeb adhesives uas yuav muab high-zoo clutch qhov chaw thaum lub sij hawm los ua ke. Nws yog rau lub hom phiaj no kub yaj nplaum yog siv, uas yog ib tug granular cov khoom, kev yuav khoom ib lub hnab yas mob los ntawm cov cua kub thiab sai heev solidifies raws li qhov txias.

qauv

Cov khoom ntawm cov khoom no yog muab nrog tshwj xeeb Cheebtsam nyob rau hauv muaj pes tsawg leeg. Nyob rau hauv feem ntau adhesives yog manufactured nyob rau hauv lub hauv paus ntawm vinylacetate-ethylene copolymer.

No thaum lawv tseem muab cov khoom:

• nplaum zog;
• zoo toughness;
• cohesive zog;
• zoo meej compatibility nrog rau lwm cov ntaub ntawv.

Yuav kom ntxiv txhim kho lub zog ntawm cov khoom, lub kub yaj nplaum tej zaum yuav muaj kuj ntau yam:

• fillers;
• modifiers;
• plasticizers;
• antioxidants.

Tag nrho cov no muab qhov kawg cov ntaub ntawv uas zoo wettability ntawm chaw, zoo elasticity, tsawg shrinkage, tsis tshua muaj thermal degradation, thiab tshaj.

xaiv cov nta

Yuav kom qhov kub yaj nplaum rau cov npoo haum txig, koj yuav tsum coj mus rau hauv tus account nta ntawm cov ntaub ntawv rau hauv ob sab phlu ntawm vaj huam sib luag qhov chaw. Yog hais tias nyob rau hauv raug yog feem ntau tsuas yog siv tej hom ntawm ntug, koj tsuas yuav tau siv kub yaj nplaum pom zoo rau tej khoom. Nyob rau hauv cov ntaub ntawv ntawm lub ntau hom ntawm npoo nrog tib zaus yuav tsum tau xaiv universal nplaum uas yog haum yog tib yam rau ib yam khoom.

Tau txais kev pab kuj muaj adhesives sau thiab unfilled. Tsis ntev los no pheej yig dua thiab feem ntau nyiam xim, tab sis lawv ceev npaum li cas ntau dua, thiab yog li ntawd lub tau ntawm lub substrate yog loj. Raws li ib tug tshwm sim, uas tsis muaj nqi tsis laij nws tus kheej. Muaj tej yam teeb meem thaum xws adhesives tseem yuav tsum tau, raws li lawv yog zoo lawm ua tus sau nrog sib sib zog nqus khaubncaws sab nraud povtseg ntawm particle board.

Nta ntawm daim ntawv thov

Tsis tas li ntawd, thaum koj xaiv yuav tsum xyuam xim rau cov yam ntxwv ntawm lub nplaum. Material khoom nyob rau hauv daim ntawv ntawm cov rods, yuav tsum tau ua kom tiav melting ntawm lub chaw ua hauj lwm. Nws yog thov rau qhov chaw, maj melted los ntawm ib kawg, li no kev txhim kho qhov zoo ntawm gluing. PVC ntug thiab kub yaj nplaum ntawm YU yuav kev cob cog rua thiab nyob rau lwm yam tswvyim feem ntau ua hauj lwm rau txoj lug. Xws li ib tug embodiment yuav ua ntawv thov cov nplaum nyob rau hauv ib lub kua hauv lub xeev rau ntug, tom qab uas nws yog tauj mus rau tus neeg. Tom ntej no cladding nplaum yuav tsum tau rov melted nrog huab cua kub thiab tag nrho nrog rau lwm qhov chaw. Cov kev ceev ntawm lub li sufficiently uas tsis muaj, tab sis kuj yog ib tug tsis tshua muaj txaus nplaum, uas ntau yam tsis xws luag yog tshem tawm qhov ntxeem tau qauv tsevneeg qhov chaw.

Cov ntsiab lus uas cia qhov chaw

Thaum koj ua hauj lwm yuav tsum tsis txhob tau txuam nrog ntawm dej ntawm lub qhov chaw thiab kua nplaum, yog li tag nrho cov npoo thiab rooj tog zaum qhov chaw yuav muab tso rau hauv lub lag luam xwb ncaj nraim nrog sov warehouse. Nyob rau hauv cov ntaub ntawv ntawm txias xeev dej condenses rau Tub yees npoo thiab deteriorates lub coupling qhov chaw nrog ib tug nplaum.

kev khiav hauj lwm kub

Yuav kom kub yaj nplaum yuav muab lub zoo meej daim ntawv cog lus, koj yuav tsum mus ua hauj lwm nrog nws tsuas yog nyob rau tej yam kub. Feem ntau, cov installation yuav muab cov kev kawm ua tau zoo, tab sis nyob rau hauv tej yam tej yam kev mob ntawm kub yuav raug muab txo.

Piv txwv li, yog hais tias:

• xub ntiag ntawm burnt nplaum txheej nyob rau hauv cov hlab;
• tsawg ceev cov kua nplaum me nyuam mus rau qhov chaw ntawm daim ntawv thov
• tuav txias Cheebtsam.

Lub nuances ntawm daim ntawv thov

Yuav ua kom pom adhesion, ib tug txheej ntawm nplaum thov yuav tsum yog tus yam thickness. Yog hais tias ntau dhau heev lawm kua nplaum, nws yuav tsum tau squeezed tawm ib ncig ntawm lub sawv thaum pressed, tab sis yuav muab ib tug zoo dua tuav. Ib tug me me muaj pes tsawg tus neeg ua hauj lwm yuav tsis ua rau kab mob sib kis ntawm chaw ua hauj lwm cov chaw, tab sis nws yuav tsis muab ib tug zoo degree ntawm tsevneeg. Tom qab ua ntawv thov cov ntaub ntawv ntawm lub workpiece tam sim ntawd xa mus rau lub nip, uas yog nqa tawm nrog tus steel xovxwm chais.

niaj hnub ntaub ntawv

Niaj hnub no pom tau hais tias qhov zoo tshaj plaws kub yaj cov nplaum rau cov PVC, polyurethane cov ntaub ntawv. Xws li ib tug muaj pes tsawg leeg tau sau tag nrho cov zoo ntawm cov pa thiab cov tshuaj tiv thaiv cov khoom. Polyurethane nplaum yog tau solidify tsis tsuas yog nyob rau hauv lub cev los ntawm kub, tab sis kuj nyob rau hauv cov tshuaj. Tshwj xeeb izoatsitaty nyob rau hauv nplaum qauv tsim tus ntoo khaub lig-kev mus nyob rau hauv tus ntawm humidity, yog li xa muaj pes tsawg leeg rau hauv ib lub peb-dimensional qauv ntawm cov clutch.

Tag nrho cov kev kho ntawm xws li ib tug khoom kav ib ob peb hnub, tab sis nws yog nyob rau lwm yam:

• qhov chaw thiab cov av noo ntawm ib puag ncig;
• kub qhov chaw thiab qhov ib puag ncig;
• cov tshuaj muaj pes tsawg leeg ntawm lub nplaum.

Cia adhesives ntawm tej qauv yuav tsum tshwm sim nruj me ntsis nyob rau hauv qhuav hauv tsev nyob rau tej kub, txij li thaum nyob rau hauv tus ntawm unfavorable tej yam kev mob rau cov khoom siv loses nws cov khoom. Tiv tauj nrog dej mus muab nws yuav tsis zoo. Tom qab cov kua nplaum yog kiag li mus rau hauv cov khoom daim ntawv no, nws kuj muaj cai nyob rau hauv lub kub ntau los ntawm -30 mus +150 degrees.
