EVA Ishushe Iyungurura Umuyaga

EVA ishushe iyungurura ry'umuyaga ry'iyunguruzo ry'ibarabara-TH-311A grade-ni amata-yera, ryinshi-viscosity granules zakozwe canecane kugira ngo zishireko ivyuma vy'iyunguruzo bitagira -iboshe ku bikoresho vyavyo bikikije, ikarata, canke ivyuma. Ku 170 degree, igikoresho co kwifatanya kigaragaza umubiri uremereye-11 000-17 000 cps melt index, uburyo buhuye butuma imbunda y’ivyo kwifatanya ishobora gushiramwo umurongo uzamutse, udatera -ku ruhande rw’umurongo wa U- canke umunwa w’uruzitiro; iri buye rifata ubwo nyene igice c'akayunguruzo canke igipande c'akayunguruzo caciwe imbere y'-, rikayikwegeranya n'igicapo mu gihe ryuzuza utuvungukira dutoduto twoshobora gutuma umuntu agenda. Naho ari uburebure, igikoresho gicapura-kiragabanuka iyo gikoresheje umuvuduko w’ipompa, kigafungura neza biciye ku nzira zisanzwe zifise uburebure bwa 0,8{30}}1,2 mm ku meza yikora canke imashini zikora ibice 100–300 ku munota. Igihe co gufungura kiringaniye c’amasegonda 4–10 giha abakoresha idirisha rihagije gusa ryo gutunganya ivyuma imbere y’uko amabombo afunga, hanyuma iyo nkuru ironka inkomezi zo gukora mu masegonda munsi ya 15 n’ubumwe bushitse mu minota itanu, ku buryo amabara ashobora guca aja ku kibanza gikurikira co gukoraniramwo ata bikoresho vyo gufatanya. Igipande gikize kiguma gishobora guhinduka kuva kuri –20℃gushika kuri +65℃, kigafata ukunyiganyiga kuva ku bikoresho vy’umuyaga n’uguhinduka kw’ubushuhe mu bikoresho vyo hejuru y’urusengero ata gusenyuka canke gusenyuka. Umunuko ni muto cane, VOC zisohoka ziri munsi ya 150 μg g−1, kandi iyo miti ntirimwo ibintu bishobora gutuma umuriro udatera, formaldehyde, ivyuma biremerera n’ibintu bigabanya umuriro, bihuye n’amategeko ya RoHS, REACH na FDA 21 CFR 175.105 y’ibifungurwa bitaziguye. Muri make, TH-311A grade EVA hot melt for bonding y’iyunguruzo ry’umuyaga itanga umuti w’uburemere bwinshi, wuzuza ibihengeri, usukura ibidukikije uhindura ugukingira uruzitiro mu gikorwa c’igihe kimwe, ata myanda.
