Yiziphi izinguquko ezingathinta i-viscosity yama-adhesives ashisayo?

Siyazi ukuthipur hot ncibilika ingcina bonding object actually penetrates into the object to be bonded and combines with its molecular structure to destroy the surface layer of the object, thereby firmly bonding the two objects. So we can increase the stickiness of pur hot ncibilika ingcina by changing something?

1. Ukwelashwa nge-Surfacetreatment

Kunezendlalelo ezithile ze-carbon (ezifana nokugqwala), ungqimba oluhlanganiswe nge-chrome, ungqimba lwe-phosphating kanye ne-ejenti ye-moldrelease ebusweni bento okufanele ilandelwe. "Isendlalelo esingenamkhawulo" sizothinta ngqo amandla okuhlanganisa. Ingqimba ye-oxide ebusweni iphathwa kuqala ukuthuthukisa amandla okubopha.

2. Uburhabaxa be-Improvesurface

The roughening process of the surface of the bonded object can also affect the adhesion. If the object is too smooth, the pur hot ncibilika ingcina can penetrate less molecules, thereby reducing the bonding strength. Therefore, we can also increase the bonding strength of the hot melt adhesive by increasing the surface roughness of the bonded object.

3.Adhesivelayer ukujiya

Uqweqwe lwesiglu esijiyile kulula ukukhiqiza amabhamuza, azobangela izifo noma ukuphuka kokuqala. Ngakho-ke, singenza iglue ibe mncane ngangokunokwenzeka, ukuze sithole amandla aphezulu okubopha. Ngaphezu kwalokho, ukwanda okushisayo kwesendlalelo esinamathelayo esiwugqinsi ngemuva kokufudunyezwa kwenza ukucindezeleka okushisayo kubangelwe yindawo yokubopha enkulu. Kunzima ukufeza ukulimala kwamangqamuzana ebusweni besiza okuhlanganisa, futhi ukubopha ngeke kube namandla.

4. ingcindezi

Lapho uxhuma, faka ingcindezi endaweni yokubopha ukwenza ukunamathela okushisayo kugcwalise izimbobo ku-bondingsurface, futhi kugelezele nasemigodini ejulile nakuma-capillaries ukunciphisa amaphutha okubopha. Ngakho-ke, ingcindezi efanele ngesikhathi sokubopha nayo ingakhuphula ubuso bento eboshiwe. Igesi iyaphunyuka, inciphise indawo yokubopha yomgodi futhi inyuse ukuqina kokuqina.
