Ezona ngxaki ziphambili zokupakishwa okuguquguqukayo kwicala lophuhliso elizayo (ukupakishwa okuzenzekelayo) Isiqendu2

2, Ingxaki ye-friction coefficient

I-friction kwi-package ihlala idonsa kunye nokuchasana, ngoko ke ubukhulu bayo kufuneka bulawuleke phakathi koluhlu olufanelekileyo.Iikhoyili zokupakisha ngokuzenzekelayozifunwa ngokubanzi ukuba zibe ne-coefficient encinci ye-friction yangaphakathi kunye ne-coefficient ye-friction yangaphandle efanelekileyo.I-coefficient ye-friction yangaphandle enkulu kakhulu iya kubangela ukuchasana okugqithisileyo kwinkqubo yokupakisha, kubangela ukuguqulwa kwezinto ezolula.Ukuba incinci kakhulu, inokubangela ukuba indlela yokutsala ityibilike, ibangele ukulandelwa okungachanekanga kunye nokusika kweliso lombane.Nangona kunjalo, i-coefficient ye-friction yoluhlu lwangaphakathi akufanele ibe yincinci kakhulu.Ukuba i-coefficient ye-friction yoluhlu lwangaphakathi lweminye imishini yokupakisha incinci kakhulu, ukupakishwa kwezinto eziphathekayo kuya kungazinzi ngexesha lokwenziwa kwengxowa kunye nokubumba, okubangelwa ukungahambi kakuhle;Yefilimu edibeneyo yeukupakisha strip, i-coefficient ye-friction encinci kakhulu yomaleko wangaphakathi inokubangela ukutyibilika kwethebhulethi okanye i-capsule, okukhokelela ekumiseni okungachanekanga kwe-blank.I-coefficient ye-friction yomgca wangaphakathi wefilimu edibeneyo ixhomekeke kumxholo we-agent yokuvula kunye ne-smooth agent ye-inner layer material, kunye nokuqina kunye nokuguquguquka kwefilimu.Umphezulu we-corona wonyango, ubushushu bokunyanga kunye nexesha ngexesha lenkqubo yokuvelisa kwakhona kuchaphazela i-coefficient ye-friction yemveliso.Xa ufunda i-coefficient ye-friction, ingqwalasela ekhethekileyo kufuneka ihlawulwe kwimpembelelo enkulu yokushisa kwi-coefficient ye-friction.Ngoko ke, akuyimfuneko kuphela ukulinganisa i-coefficient ye-friction yeizinto zokupakishakwiqondo lobushushu begumbi, kodwa kunye nokuphanda i-coefficient yokukhuhlana kweyona ndawo isetyenziswayo kwiqondo lobushushu.

3. Ingxaki yokutywinwa kobushushu

Ukushisa okuphantsi kokutywinwa kokusebenza kokushisa kunqunywe ngokukodwa ngokusebenza kwe-resin yokutywina ukushisa, kwaye kunxulumene noxinzelelo.Ngokubanzi, iqondo lobushushu le-extrusion liphezulu xa likhupha kwaye lidibanisa, kwaye ubushushu obuphantsi bokutywinwa kokusebenza kwesixhobo kuya kuncitshiswa ukuba unyango lwe-corona lunamandla kakhulu okanye ifilimu imiswe ixesha elide kakhulu.I-viscosity ye-Thermal isetyenziselwa ukuchaza amandla okuxutywa kwe-melting surface yomgangatho we-heat seal ngokumelene namandla angaphandle xa ipholile ngokupheleleyo kwaye iqiniswe emva kokutywinwa kobushushu: lo mandla wangaphandle udla ngokuvela kumatshini wokupakisha wokuzalisa ngokuzenzekelayo.Ngoko ke,ifilimu ehlanganisiweyo imathiriyeli ejijelweyoesetyenziselwa ukupakisha okuzenzekelayo kufuneka ibe yinto yokutywina ukushisa kunye ne-viscosity efanelekileyo ye-thermal.Ukumelana nongcoliseko ukutywinwa kobushushu, okwakwaziwa njengokuqukwa kokutywinwa kobushushu, kubhekiselele ekusebenzeni kokutywinwa kobushushu xa umphezulu oshushu unamathela kumxholo okanye ezinye izinto ezingcolisayo.Ifilimu edibeneyo ikhetha i-resin ezahlukeneyo zokutywinwa kobushushu ngokwezinto ezahlukeneyo zokupakisha, oomatshini bokupakisha kunye neemeko zokupakisha (ubushushu, isantya, njl.).Omnye umaleko wokutywina ubushushu awunakusetyenziswa ngokufanayo.Izixhobo zokutywina ubushushu obuphantsi ziya kukhethwa kwiipakethi ezinokumelana nobushushu.Ukupakisha okunzima, izinto zokutywinwa kobushushu ezinamandla okutywinwa kobushushu obuphezulu, amandla omatshini aphezulu kunye nokusebenza kakuhle kwempembelelo kuya kunyulwa.Kumatshini wokupakisha ngesantya esiphezulu, izixhobo zokutywina ubushushu obuphantsi kunye nezinto zokutywinwa kobushushu obunamandla aphezulu e-thermal viscosity ziya kukhethwa.Kwiimveliso ezinongcoliseko olomeleleyo ezifana nomgubo kunye nolwelo, izixhobo zokutywina ubushushu ezinokumelana nokungcoliseka okulungileyo ziya kukhethwa.
