Maro aan tow lahayn oo ka samaysan polypropylene biodegradable

Sababo la xiriira qaab dhismeedka molecular kaarboonka hal bond ee isku xidhan ee kaarboonka ah, qaab-dhismeedkiisa molecular ee qaraabada ah waa mid deggan oo ay adagtahay in si degdeg ah loo dhimo. Iyada oo dharkan fudud ee polypropylene spunbond nonwoven uu keeno ku habboonaanta wax soo saarka dadka iyo nolosha, waxay sidoo kale keentaa wasakhowga deegaanka qaarkood. Sidaa darteed, diyaarinta iyo cilmi-baarista deegaanka u saaxiib iyo biodegradable polypropylene ka samaysan spunbond dhar aan tow lahayn ayaa si gaar ah muhiim u ah. Polylactic acid waa polymer-dabiiciga ah oo leh isqabqabsi aad u wanaagsan iyo sifooyin farsamo. Waxaa lagu dari karaa alaabada ceyriinka ah ee polypropylene si loo diyaariyo bidegradable polypropylene composite spunbond maras aan tow lahayn, taaso hoos u dhigaysa wasakhda deegaanka ee ay keento polypropylene spunbond dhar aan tow lahayn.

Waxqabadka polipropylene ka samaysan spunbond dhar aan tow lahayn

Inta lagu guda jiro diyaarinta biodegradable polypropylene composite spunbond dhar nonwoven, arrimo ay ka mid yihiin xawaaraha bamka cabbirka, kulaylka kulaylka kulul, iyo heerkulka miiqdaan saamayn weyn ku yeelan karaan sifooyinka jireed ee dharka nonwoven spunbond. Ku hagaaji sida waafaqsan shuruudaha macaamiisha sida miisaanka, dhumucda, xoogga xajinta, iwm.

Saamaynta cabbiraadda xawaaraha bamka

Iyada oo la dejinayo xawaaraha bamka cabbirka ee kala duwan, sifooyinka fiber-ka ee fiilooyinka isku dhafan ee la diyaariyey, sida cufnaanta tooska ah, dhexroorka fiber-ka, iyo xoogga jabka fiber-ka, ayaa la falanqeeyay si loo go'aamiyo xawaaraha cabbiraadda ugu habboon ee waxqabadka fiilooyinka fiilooyinka isku dhafan ee la diyaariyey. Isla mar ahaantaana, iyada oo la dejinayo xawaaraha bamka cabbirka kala duwan si loo falanqeeyo tilmaamayaasha waxqabadka sida miisaanka, dhumucda, iyo xoogga xajinta ee dharka la isku daray ee spunbond nonwoven, xawaaraha bamka cabbiraadda ugu fiican waxaa lagu heli karaa iyada oo la isku darayo sifooyinka fiber-ka iyo sifooyinka aan-xidhka lahayn ee ka samaysan spunbond dhar aan-xirmo lahayn.

Saamaynta heerkulka rogrogmida kulul

Iyadoo la hagaajinayo halbeegyada habraaca diyaarinta kale iyo dejinta miraha duuban ee kala duwan iyo heerkulka rogid kulul, saamaynta heerkulka rogid kulul ee sifooyinka fiilooyinka fiber isku dhafan ee la diyaariyey ayaa la daraaseeyaa oo la falanqeeyaa. Marka heerkulka xoojinta kulul ee mishiinka duuban uu aad u hooseeyo, fiilooyinka kulaylka leh si buuxda looma dhalaali karo, taasoo keenta qaabab aan caddayn iyo gacma xumo. Qaadashada diyaarinta polylactic acid biodegradable / wax lagu daro / polypropylene composite spunbond dhar aan-dhogorta lahayn tusaale ahaan, marka heerkulka xoojinta kululaynta uu gaaro 70 ℃, khadadka fiber-ka isku dhafan waa cad yihiin oo waxaa jira wax yar oo ku dheggan duubka, markaa 70 ℃ ayaa gaadhay xadka sare ee heerkulka xoojinta.

Saamaynta heerkulka wareega

Saamaynta heerkulka wareegyada kala duwan ee sifooyinka cufnaanta dunta isku dhafan, dhexroorka fiber-ka, iyo xoogga jabka fiber-ka, iyo sidoo kale sifooyinka dabiiciga ah ee polypropylene composite spunbond dhar nonwoven, halka hagaajinta xuduudaha kale ee habka diyaarinta.

Geedi socodka tignoolajiyada ee socodka polypropylene biodegradable ee ka samaysan spunbond dhar aan tow lahayn

(1) Jeex polylactic acid, polypropylene, iyo maleic anhydride copolymer ku tallaalka oo isku qas oo ku walaaq inta habboon;

(2) U isticmaal qalabka wax saara ee granulation iyo mishiinka wareegta si aad ugu wareegtid;

(3) Ku sifee filtar dhalaalaysa oo samee shabag ka hooseeya waxqabadka bamka cabbirka, qalajiyaha, iyo socodka hawada xawaaraha sare ee socodka hawada;

(4) Soo saar marado aan dun lahayn oo u qalma spunbond iyada oo loo marayo xoojinta isku xidhka duuban ee kulul, dabaylaha, iyo goynta gadaal.
