Ndezvipi zvakanakira zvekunamira zvinonyunguduka zvichienzaniswa neglue dzechinyakare?

1. Viscosity

Melt viscosity chiratidzo chakakosha chehot melt adhesives, nokuti mashizha anopisa anonyunguduka anofanira kushandiswa nerubatsiro rwemichina yekunamatira inopisa inonyunguduka. Kazhinji kutaura, maindasitiri akasiyana uye akasiyana mashandisiro ane akasiyana anopisa anonyungudutsa adhesive maumbirwo.

 

2. Kurapa nguva

Iyo inopisa yakanyunguduka glue inoshandisa kupisa sepakati, uye glue inosungirirwa mushure mekutonhora. Naizvozvo, kutarisisa kunofanirwa kubhadharwa kune kutonga kwekushanda nguva iri kushandiswa.

Kurapa nguva: inoreva nguva pfupi iyo inogona kuumba chisungo mushure mekunamatira. Nguva yekuvhura: inoreva nguva yakareba inobvumirwa mushure mekunamatira kudzvanya.

 

3. Kuramba kwekushisa

EVA inopisa melt adhesive inogumira nehunhu hwayo, saka kupisa kwayo kupisa kuri pakati pe40°c uye 65°C pasi pemamiriro ekushisa anogara aripo. Chikonzero chikuru ndechekuti iyo yekunyungudika yeEva iri zvakare pakati pe40°c uye 70°C. Pur heat Kudzivirira kupisa kwekunyunguduka kwakasimba kwakasimba, kusvika ku100℃.

 

4. Kunamatira

Paunenge uchitaura nezvekunamatira, chinonyanya kukoshesa chiri pazvinhu zvinosungirirwa. Zvinoenderana neyakajairwa kupatsanurwa, kune simbi, plastiki, pepa, huni, nezvimwewo kana zvinoenderana nemamiriro ekubatanidza anodiwa nemutengi. Sarudza muenzaniso wakakodzera uye chigadzirwa chakakodzera. , Inogona kudzivirira matambudziko mushure uye kuchengetedza nguva yebasa.
