Mazgu Ghakwamba Ghakukhwaskana na Chipatala Hot Melt Adhesive

Medical hot melt adhesive ni chinthu icho chikuvikilira chilengiwa chomenechomene icho chikupangika na vinthu vya polima, chomenechomene chikugwiriskirika nchito pakukolerana na kuŵika vinthu vyakuvikilira vyachipatala nga ni masiki ghachipatala, magawuni ghakuchitira opareshoni, na mathumba ghakuŵikamo sterilization. Ivyo vikupangika, mwa kusazgako vigaŵa vinyake vyakuzirwa nga ni ufu wa chisulo cha carbonyl wakusinthika na polyethylene glycol graft copolymer, vikupanga chigaŵa chitatu cha mtundu wa mtundu kuti vikhozgere katundu wa makina, kuŵa na mtundu wa luso wa 16KN / m na 180℃U {d pe} streth. Ivyo vikupangika vikukolerana na malango gha FDA gha pa charu chose, vikupangika na solvent-, ndipo vyajumphapo pa kukhozgeka kwa UV irradiation kuti vileke kuŵa vya chikasu, kukwaniska chitetezo cha tizirombo na kutozga chikumba cha vipangizo vyachipatala. Mu mapulogalamu gha chipatala, vikulongora kuti vikulimbana na -condensation na anti-fouling ndiposo vikupangiska kuti khungu liŵe laubwezi, ndipo ivi vikumazga suzgo la kutaya kumamatira mu vinthu vyakupangika na ŵanthu ŵa chikhalidwe pa nyengo yakuchita maseŵero ghakukhozga thupi.

Ivyo vikupangika na polystyrene triblock copolymer (SIS) ivyo vikupangika na polyethylene glycol (PEG) nga ni chinthu chakwamba, ndipo vikusazgapo tetraethyl orthosilicate kuti viŵe vyakukhozga. Nthowa iyi yili na 38% ya mafuta ghakupangika na hydrogenated na 12% ya mafuta gha naphthenic, ndipo yikuŵikamo resini ya superabsorbent polymer (SAP) kuti yipangiske nthowa yakulongozgera chinyezi.
