PUR Kub Melt Tshuabyog ib qho khoom siv tshwj xeeb uas tsim los rau yaj, xa tawm, thiab siv PUR kub yaj nplaum - cov khoom siv polyurethane reactive uas kho tau los ntawm ob theem: lub cev pib adhesion thiab tshuaj lom neeg ntoo khaub lig- txuas ua los ntawm ya raws hauv huab cua. Cov txheej txheem kev kho dual no tau teeb tsa nws sib nrug los ntawm cov tsoos EVA kub yaj tshuab, uas tsuas yog tso siab rau lub cev txias kom tsim cov ntawv cog lus. Cov tshuaj tua kab mob (uas siv sijhawm 24-72 teev kom ncav cuag lub zog tag nrho) tsim ib daim ntawv cog lus uas muaj cua sov-tiv taus (dhau 150 degree, piv rau 80-120℃rau EVA), tsis muaj dej, thiab tsis tuaj yeem rov qab tau-ua rau nws zoo tagnrho rau cov ntawv thov uas yuav tsum tau siv ntev -lub sij hawm ntev, los yog qhov kub thiab txias siab - ib puag ncig kev nyuaj siab.
Sealed Melting System: Lub plawv ntawm lub tshuab, muaj ib lub hermetically kaw melting tank los yog nias phaj nrog nitrogen tiv thaiv (kom cais molten kua nplaum los ntawm huab cua). Lub tank yog ua los ntawm siab - kub- resistant alloy los yog SUS304 stainless hlau, nrog Teflon txheej los tiv thaiv cov kua nplaum carbonization thiab adhesion. Cov khoom cua sov muab cov cua sov sib xws rau 110-130℃(qhov zoo tshaj plaws melting ntau rau PUR nplaum).
Precision Conveying System: Tau nruab nrog lub siab -cov twj tso kua mis precision (ua haujlwm kom ruaj khov nyob rau hauv siab - viscosity kua nplaum) thiab cov kav xa hluav taws xob kom tswj tau qhov kub thiab txias thaum lub sij hawm thauj cov kua nplaum. Lub kaw lus nta kev hloov pauv ceev ceev los tswj cov kua nplaum tawm, kom ntseeg tau tias daim ntawv thov tsis sib xws thiab txo cov khoom pov tseg. Ib lub raj xa dej rov qab siv cov kua nplaum ntau dhau, ntxiv txo cov khoom poob.
Daim ntawv thov System: suav nrog cov phom phom sib hloov thiab cov nozzles (strip, kauv, fiber ntau) kom ua tiav cov dot, kab, lossis daim ntawv thov saum npoo. Lub lim dej zoo tshem tawm cov impurities los tiv thaiv nozzle clogging, thiab lub kaw lus muaj adjustable txheej dav (60mm-550mm) thiab thickness (0.1mm-2mm) rau ntau yam siv.
Txheej Txheem Ua Haujlwm: Dual -Theem Curing rau Superior Bonds
Cov txheej txheem ua hauj lwm ntawm PUR Kub Melt Tshuab yog streamlined tab sis tshwj xeeb, tsim los leverage cov khoom reactive tshwj xeeb ntawm PUR nplaum:
Adhesive Loading:
PUR adhesive (granular, block, or in drums) is loaded into the sealed melting system-either the press plate (for drum-fed models) or melting tank (for small-batch models).
Melting & Kev rho tawm:
Lub tshuab ua kom sov cov nplaum rau 110-130 degree, melting nws mus rau hauv lub xeev ua kua. Lub kaw lus kaw thiab tiv thaiv nitrogen tiv thaiv huab cua los ntawm kev tiv thaiv cov kua nplaum molten, tsis txhob muaj tshuaj tua ntxov ntxov.
Precise Conveying:
Lub iav twj tso kua mis xa cov nplaum nplaum los ntawm cov raj xa hluav taws xob rau cov phom nplaum, tswj qhov kub thiab txias kom zoo rau daim ntawv thov sib xws.
Application & Initial Bonding:
Cov phom nplaum siv cov nplaum nplaum rau hauv lub substrate, thiab cov nplaum ua kom txias sai heev los ua ib daim ntawv cog lus ntawm lub cev - tso cai rau lub sij hawm qhib qhib (ntau txog kaum rau vib nas this) rau kev hloov txoj hauj lwm.
Tshuaj Kho Mob: Cov nplaum nplaum nplaum absorbs noo noo los ntawm huab cua, ua rau tus ntoo khaub lig -txuas cov tshuaj tiv thaiv uas tsim ib qho irreversible, siab - zog daim ntawv cog lus. Kev kho tag nrho yuav siv sijhawm 24-72 teev, ua rau muaj kev sib cog lus uas muaj cua sov- tiv taus, tsis muaj dej, thiab ruaj khov.
