Okunamathelayo Okuphezulu Okushisayo Kwezinhlayiyana Zeglue

Ama-granules eglue anamathelayo aphezulu ashisayo angu-TH{1}}102S agqamile-amhlophe, aluthuli{3}}izinhlamvu zamahhala ezisekelwe ku-metallocene{4}}i-catalyzed polyolefin backbone eyakhiwe ngenjongo eyodwa: ukudala ibhomu{5}}amabhondi obufakazi phakathi kwesitokwe sebhokisi eliboshwe kanye nokupakishwayo{7}} Ngenxa{10}}ye-site catalyst eyodwa, amaketanga e-polymer avamile kakhulu, ngakho okunamathelayo kuthuthuka ngokushesha lapho iphuma emlonyeni, nokho ihlala izinzile ngokushisa kwezinsuku ku-160℃ngaphandle kokwakheka kwe-char noma ijeli. Le chemistry eyingqayizivele ivumela ama-granules eglue anamathelayo aphezulu ancibilike ashisayo ukuthi abe manzi futhi abambelele ngokuqinile ku-PP, PET, UV{11}}i-varnish{11}}namafilimu okuthinta athambile{12}, aletha amabhondi e-fibre{13}}adabulayo asinda ekuqineni okujulile, ukwehla nokuhlolwa kokudlidliza kuze kufike ku- -30℃.

Ngoba i-metallocene polyolefin inokuminyana okuphansi (0.92 g cm-³) kune-EVA evamile noma ukuncibilika kwenjoloba-okususelwa ekushiseni{3}}, ikhilogremu ngayinye ye-TH{6}}102S ikhiqiza kufika ku-8 % wemayela ngaphezulu, ukusika ukusetshenziswa kweglue kanye nezindleko zempahla ngaphandle kwamandla e-sacrificingcarton{70}{1} Ukwakheka kuqinile ngo-100 %, kuqukethe izincibilikisi eziyiziro, ama-plasticizers noma ama-heavy-metal catalysts, futhi kunesitifiketi se-ROHS, REACH, ngakho abaguquli bangakwazi ukukusebenzisa kumabhokisi okudla, ezimonyo nakwezemithi ngaphandle kokudluliswa kwephunga noma ingozi yokufuduka.

Emgqeni,-i-viscosity encibilikayo ephansi emaphakathi (1 500–2 700 cPs ku-170℃) ivumela ama-granules eglue anamathelayo aphezulu ancibilike afafaze ngamamojula e-Nordson, Robatech noma e-ITW njengamaphethini amahle, aphenduphendukayo noma athungayo anokucindezela okuncane futhi angabikho inkungu, egcina imibhobho yokukhiqiza{4} ehlanzekile iviki lonke{4}} 3-Iwindi lesethi yokuminyanisa isekhondi elingu-5 lifana nesivinini esigoqayo sokugoqa sesimanje-esizungeze, ithreyi{9}}ifomu lokupakisha{12}}lomkhono-lomkhono{12}, kuyilapho izinga lokushisa eliphansi lohlelo lokusebenza (140-170℃) linciphisa ukudonsa kwamandla kufika ku-15 % uma kuqhathaniswa namasistimu erabha ane-viscosity ephezulu.

Ngamafuphi, i-TH{1}}102S inika amaphakheji inhlanganisela eyivelakancane yokunamathela okunonya kufilimu{2}}amabhodi anamathelisiwe, ukumelana okubandayo{3}}okuguquguqukayo, ukuthobela indawo ezungezile kanye nezindleko ezilinganisekayo{4}}{5}}ngokonga kwebhokisi ngalinye{6}}okubenza babe inketho yokuqala yokunamathisela enamathiselwe emshinini wokunamathisela odongeni futhi igcine ingcina yemoto eqinile izandla.

Amashadi ashisayo: ama-granules eglue anamathelayo aphezulu, eChina abakhiqizi bezingcwecwe zeglue enamathelayo ephezulu, abahlinzeki, imboni
