1. Lub tshuab txheej nplaum kub yaj: Siv cov kua nplaum uas muaj viscous, coated rau ntawm lub substrate, feem ntau muaj cov khoom lamination, lub tshuab uas tuaj yeem laminating lwm lub substrate thiab cov substrate glued. (Nws yog ib hom polymer uas tsis xav tau cov kuab tshuaj, tsis muaj dej, thiab yog 100% khov thiab fusible. Nws khov ntawm chav tsev kub. Nws ua flowable thiab muaj qee qib ntawm cua sov thiab yaj.)
2. Cov txiaj ntsig ntawm cov txheej txheem: tsis tas yuav siv cov khoom siv ziab, siv hluav taws xob tsawg: tsis muaj cov kuab tshuaj (cov nplaum kub yaj yog 100% cov khoom khov), tsis muaj kuab paug, thiab tus neeg teb xov tooj yuav tsis raug rau ntau yam formaldehyde vim yog kev ntxuav cov kua nplaum seem. Piv nrog cov nplaum uas siv cov kuab tshuaj thiab cov nplaum uas yaj tau hauv dej, nws muaj cov txiaj ntsig zoo, daws tau cov teeb meem ntawm cov txheej txheem ib txwm muaj, thiab yog cov cuab yeej tsim khoom zoo tshaj plaws rau kev txhim kho kev lag luam txheej thiab kev sib xyaw.
3. Kev kho cov nplaum uas muaj cov tshuaj yaj thiab cov dej yuav tsum tau muaj lub qhov cub (lossis lub qhov cub uas twb muaj lawm yuav tsum tau kho dua tshiab), thiab siv ntau qhov chaw cog qoob loo, thaum lub Hoobkas siv zog ntau ntxiv; nws yuav tsim cov dej khib nyiab thiab cov av nkos ntau dua; Cov kev cai tsim khoom thiab kev ua haujlwm nruj dua; qhov tsis zoo ntawm cov kua nplaum yaj yog qhov tseeb, uas yog, nws yog tus phooj ywg ib puag ncig heev (feem ntau ntawm cov tshuaj yaj yog qhov txaus ntshai). Cov nplaum uas muaj cov tshuaj yaj muaj kev ua qias tuaj rau ib puag ncig loj heev. Nrog rau kev txhim kho ntawm tib neeg txoj kev paub txog ib puag ncig thiab kev tsim thiab kev txhim kho ntawm cov cai lij choj cuam tshuam, kev siv cov nplaum uas muaj cov tshuaj yaj poob qis ntawm qee qhov nqi txhua xyoo. Cov kua nplaum uas muaj dej muaj qhov tsis zoo xws li tsis kam dej, cov khoom siv hluav taws xob tsis zoo, lub sijhawm qhuav ntev, thiab kev siv zog ntau. Nws daim ntawv thov kuj tseem poob qis ntawm qee qhov nqi txhua xyoo. Cov nplaum kub-yaj muaj qhov zoo ntawm kev ua haujlwm ruaj khov, kev siv cov khoom siv raw siab, kev tsim khoom sai, cov txiaj ntsig siab, cov khoom siv me me thiab kev nqis peev me me, thiab lwm yam, thiab muaj qhov nyiam hloov cov nplaum uas muaj cov tshuaj yaj maj mam.
4. Cov yam ntxwv ntawm cov nplaum kub yaj:
Cov khoom tseem ceeb ntawm cov nplaum kub yaj, uas yog cov resin yooj yim yog copolymerized nrog ethylene thiab vinyl acetate nyob rau hauv siab siab, thiab tom qab ntawd sib xyaw nrog tackifier, viscosity regulator, antioxidant, thiab lwm yam los ua cov nplaum kub yaj.
1) Feem ntau nws yog khoom khov ntawm chav tsev kub. Thaum cua sov mus rau qee qhov, nws yaj mus ua kua. Thaum txias hauv qab qhov melting point, nws sai sai ua khoom khov.
2) Nws muaj kev kho sai, tsis muaj kuab paug, muaj zog nplaum, thiab cov txheej nplaum muaj qee qib ntawm kev ywj pheej, tawv thiab tawv.
3) Cov txheej nplaum yog siv rau ntawm qhov adherend tom qab txias thiab khov, thiab nws kuj tuaj yeem ua kom sov thiab yaj.
4) Nws dhau los ua lub cev nplaum thiab tom qab ntawd lo rau qhov nplaum, nrog rau qee qib ntawm kev rov ua dua tshiab.
5) Thaum siv, tsuas yog cua sov thiab yaj cov nplaum kub yaj rau hauv lub xeev kua uas xav tau thiab siv rau ntawm qhov khoom uas yuav tsum tau lo rau.
6) Tom qab nias thiab sib txuas, kev sib txuas thiab kev kho tuaj yeem ua tiav hauv ob peb feeb xwb, thiab qib kev tawv thiab txias thiab ziab tuaj yeem ua tiav hauv ob peb feeb xwb.
7) Vim tias cov khoom nws tus kheej yog khov kho, nws yooj yim rau kev ntim khoom, kev thauj mus los thiab kev khaws cia.
8) Tsis muaj kuab tshuaj, tsis muaj kuab paug, tsis muaj tshuaj lom.
9) Thiab qhov zoo ntawm cov txheej txheem tsim khoom yooj yim, tus nqi ntxiv siab, viscosity siab thiab lub zog, thiab kev ceev ceev yog nrov heev.
10) Cov nplaum kub yaj muaj kev ua haujlwm ruaj khov, kev siv cov khoom siv raw siab, kev tsim khoom sai thiab cov txiaj ntsig zoo.
11) Qhov zoo ntawm thaj chaw khoom siv me me thiab kev nqis peev me me.
