Mounting ua npuas ncauj los ntawm ib txwm txhais tau tias ntawm kev sib khi lub qhov rais qhib tau ntev dhau mus rau hauv cov xwm txheej ntawm cov khoom siv hauv tsev tag nrho, uas tau siv dav hauv ntau hom kev ua haujlwm. Ntau yam kev siv ntawm cov khoom no kuj txiav txim siab qhov xav tau ntawm kev sib txawv ntawm kev siv thev naus laus zis ntawm nws cov khoom siv. Txawm li cas los xij, qhov sib txawv ntawm cov txheej txheem ua npuas dej yog ntau yam ntawm cov tshuaj pleev ib ce, tsis cuam tshuam rau cov txheej txheem thev naus laus zis.

khoom siv tshuab

Cov txheej txheem tshuaj ntawm kev tsim cov polyurethane ua npuas ncauj yog siv nyob rau hauv peb theem:

• Npaj cov khoom siv raw.
• Creating active mix rau ua npuas ncauj.
• Hloov kho ntawm lub hauv paus npaj los muab qhov tsim nyog lub cev thiab tshuaj ua haujlwm.

Twb muab tso rau hauv ib qho kev txiav txim caiscov kaus poom aerosol thiab lwm cov ntim rau kev lag luam ua npuas ncauj. Rau kev txhaj tshuaj, ib qho kev sib cais thev naus laus zis kuj tau tsim los ua ib feem ntawm kev tsim cov polyurethane ua npuas ncauj siv cov cuab yeej tshwj xeeb.

Ib qho tseem ceeb ntawm cov txheej txheem tsim khoom yog kev tswj cov txheej txheem ua npuas dej polymerization. Nyob rau theem tsim khoom tseem ceeb, nws yuav tsum tau ua npuas ncauj tau txais cov qauv xav tau nrog cov npoo txaus ntawm rigidity thiab elasticity. Txhawm rau txhawb nqa qee yam khoom thiab cov yam ntxwv, cov kev hloov kho tshwj xeeb thiab cov yas yas tuaj yeem muab ntxiv rau qhov sib tov, uas ua rau kom cov khoom tshwj xeeb, xws li hluav taws kub lossis dej tsis kam.

Raw khoom rau kev tsim

Hauv kev txiav txim siab dav dav, cov khoom siv raw rau kev tsim cov polyurethane ua npuas ncauj hais txog polyester muaj pes tsawg leeg, cov khoom uas yog tsim los ntawm cov nroj tsuag tshuaj nyob rau hauv tshwj xeeb tej yam kev mob. Ua npuas ncauj manufacturers yuav cov khoom siv raw no thiab siv nws los npaj cov khoom sib tov raws li lawv cov zaub mov txawv. Cov khoom xyaw twg tsim cov khoom siv raw? Cov ntsiab lus tseem ceeb thiab feem ntau yog polyesters, propellants, isocyanates, polyols thiab polyisocyanate nrog ntau yam tshuaj ntxiv. Piv txwv li, txhawm rau ua kom muaj qee qhov kev tawm tsam ntau ntawm cov pab pawg sib txawv ntawm cov khoom, catalysts tuaj yeem ntxiv ntxiv. Feem ntau, tus naj npawb ntawm cov khoom ntawm polyester muaj pes tsawg leeg tuaj yeem ncav cuag kaum, suav nrog cov khoom uas tswj cov txheej txheem tsim tshuaj lom neeg.

khoom siv

Tswjconveyor kab rau zus tau tej cov polyurethane ua npuas ncauj muaj cov nram qab no functional modules:

• Semi-automatic dispenser. Muab lub hom phiaj xa khoom ntawm cov khoom sib tov rau lwm cov khoom siv hauv nruab nrog cev thiab cov khoom siv, nrog rau cov thooj voos kheej kheej. Qhov nruab nrab ntau npaum li cas txawv ntawm 250 txog 450 ml.
• Valve sealer. Equips thooj voos kheej kheej nrog ua npuas ncauj dispensers.
• Pump. Kev teeb tsa ntawm cov servomotors uas ua kom muaj kev txav ntawm qhov sib xyaw ua ke raws li kev xa khoom siv thev naus laus zis.
• Rotary module. Universal unit rau sau ntim nrog kua sib tov thiab propellant roj. Chav tsev no nyob ze rau cov khoom siv tsis siv neeg rau kev tsim cov polyurethane ua npuas ncauj nrog cov khoom siv, uas, nyob rau hauv tib txoj kev thev naus laus zis, ua cov dej num ntawm kev sau thiab dov aerosol poom.

Ntxiv rau, cov chaw tsim khoom niaj hnub no tau dav dav nrog cov cuab yeej ntsuas los tswj kev ua haujlwm thiab lub xeev ntawm kev sib xyaw. Piv txwv li, cov txheej txheem ntawm cov khoom siv xws li micrometers, ntsuas ntsuas siab, ntsuas qib thiab ntsuas ntsuas kub.

Cov khoom ntawm polyurethane ua npuas ncauj

Nyob rau hauv qhov muaj pes tsawg leeg koj tuaj yeem pom cov khoom sib txawv me ntsis ntau dua li cov khoom siv tshuaj raw khoom los ntawm cov polyester muaj pes tsawg leeg tau tsim. Qhov no yog vim cov theem pib ntawm kev ua thiab kev hloov kho ntau lawm, vim tias ib pawg tshwj xeeb ntawm cov khoom siv nrog cov cim "A" thiab "B" twb tau tsim. Thawj pab pawg yog tsim los ntawm hydroxyl-muaj kua, uas, thaum ua ke nrog "B", tsim ib tug active polyurethane ua npuas ncauj.hauv paus. Nws tseem yog ib qho tseem ceeb uas yuav tsum nco ntsoov qhov sib thooj ntawm cov tshuaj sib tov rau cov khoom siv roj, uas tseem ua rau ib feem ntawm aerosol tuaj yeem. Propylene yog siv los ua ib qho kev txhawb nqa - nws yog cov roj tsis muaj xim uas tau txais los ntawm cov roj refining los ntawm txoj kev pyrolysis. Nyob rau hauv cov kaus poom tshuaj tsuag, feem ntau nws yog nyob ze rau ntawm caj dab, tab sis qhov tseeb txoj hauj lwm yog nyob rau hauv uas lub active loj nyob rau saum toj. Vim li no, nws raug nquahu kom tig lub tuaj yeem rov qab ua ntej qhib lub valve.

Kev ua haujlwm ntawm polyurethane ua npuas ncauj

Polyester sib tov paub txog mus dhau ntau theem thev naus laus zis nrog kev ua haujlwm thiab hloov kho. Kev npaj ua tib zoo ntawm mounting ua npuas ncauj hauv kev tsim khoom ua rau nws ua tau raws li hauv qab no:

• Sealing peev.
• rwb thaiv tsev kub.
• High adhesive zog (stickiness).
• Mechanical zog.
• Txhim kho lub suab nrov txo cov nyhuv.
• Machining pliability.

Yog tias peb tham txog cov ntsiab lus tsis muaj zog ntawm kev ua npuas ncauj, ces qhov kev xav txog cov khoom no tsis muaj kev nyab xeeb los ntawm ib puag ncig kev pom tau ntev tau tsim. Cov kev ntshai li no puas tsim nyog? Nws yuav tsum raug sau tseg tias ib tug neeg niaj hnub tau ntsib nrog ntau hom thiab hom polyurethane ua npuas ncauj txij thaum yau. Txawm li cas los xij, qhov no siv rau cov khoom siv kho mob thiab tshuaj. Thiab tib yam mus rau hardened ua npuas ncauj, uas tsis muaj teeb meem. Txawm li cas los xij, thaum melted nyob rau hauv tshav ntuj ncaj qha los yog nyob rau hauv cov khoom cua sov tej yam kev mob, lub npuas yuav tso tawm tsis xav tautshuaj lom.

Cov tuam txhab loj ntawm polyurethane ua npuas ncauj

Cov tuam txhab txawv teb chaws teeb tsa cov qauv hauv ntu no, ua kom pom cov khoom tsis zoo. Lub tuam txhab Belgian Soudal thiab German Kim Tec tuaj yeem raug ntaus nqi rau cov thawj coj hauv ntiaj teb tsim cov khoom lag luam polyurethane ua npuas ncauj. Ob lub tuam txhab tsim cov npuas dej zoo tshwj xeeb rau kev tsim kho thiab kev ua haujlwm. Nyob rau hauv domestic sector, ua ntej ntawm tag nrho cov, nws yog tsim nyog sau cia lub Tula chaw tsim tshuaj paus Profflex. Raws li lub hom phiaj no, ntau yam khoom siv hauv tsev thiab cov kws tshaj lij tau tsim, tsom rau cov dej num ntawm kev sib khi, kev sib khi, kev sib khi, thiab lwm yam. Tsis tas li ntawd, nws ua rau kev txiav txim siab xa mus rau cov khoom lag luam ntawm Lavxias teb sab hom DeLuxe, VladPromPen, hwm khoom, etc.

Zaj lus

Mounting ua npuas ncauj yog ib qho cuab yeej tshwj xeeb uas xav kom tus neeg siv yuav tsum muaj tsawg kawg kev paub txog cov yam ntxwv ntawm nws daim ntawv thov. Txawm hais tias niaj hnub tsim khoom ntawm polyurethane ua npuas ncauj yog nce ntxiv rau kev txhawb nqa cov txheej txheem ntawm nws daim ntawv thov kev ua haujlwm, kev ua haujlwm ntawm polyurethane ua npuas ncauj imposes ib tug xov tooj ntawm yuav tsum tau nyob rau hauv cov nqe lus ntawm installation lub koom haum. Qhov no kuj tseem siv tau rau lub sijhawm teeb tsa, thiab kev sib cuag nrog lwm cov ntaub ntawv, tsis txhob hais txog qhov muaj peev xwm nthuav dav cov npuas dej uas twb muaj lawm los ntawm kev kub ntxhov. Tab sis, txawm hais tias kev ua haujlwm subtleties thiab nuances, polyurethane ua npuas ncauj tseem ua tus pabcuam tseem ceeb rau ob tus kws tsim khoom thiab cov kws ua haujlwm hauv tsev.
