Ziziphi izizathu zokusetyenziswa kakhulu kwepolypropylene kwi-melt blown technology?

Umgaqo wokuvelisa we-meltblown fabric

Ilaphu elinyibilikayo liyinto enyibilikisa iipholima kumaqondo obushushu aphezulu kwaye emva koko izitshize kwimicu phantsi koxinzelelo oluphezulu. Ezi ntsinga zipholile ngokukhawuleza kwaye ziqina emoyeni, zenza i-high-density, i-high-efficiency network fiber network. Le mpahla ayinayo kuphela ukusebenza kakuhle kokucoca, kodwa ilula kwaye iphefumula, iyenza ifaneleke kakhulu ukusetyenziswa kwizixhobo zokukhusela ezifana nemaski.

Eyona mathiriyeli ekrwada amalaphu meltblown

Eyona mathiriyeli ekrwada yelaphu elinyibilikisiweyo yipolypropylene, eyaziwa njengezinto zePP. Okwangoku, iimaski zelaphu ezinyibilikisiweyo eziqhelekileyo kwimarike zisebenzisa ilaphu lepolypropylene elinyibilikayo njengesixhobo sokucoca. Isizathu sokukhetha i-polypropylene njengeyona nto ingundoqo ekrwada kukuba inokusebenza kakuhle kokusebenza kunye neenzuzo zeendleko, kwaye ihambelana nokusingqongileyo.

Ukongeza kwi-polypropylene, i-meltblown fabrics nayo ingenziwa ngezinye izinto ezifana ne-polyester, i-nylon, ilinen, njl. Nangona kunjalo, xa kuthelekiswa ne-polypropylene, ezi zixhobo zineendleko eziphezulu okanye ukusebenza kakubi kokucubungula, okwenza ukuba bangaphantsi kokulungeleka kwimveliso enkulu.

I-Polypropylene isetyenziswa kakhulu kwitekhnoloji enyibilikayo enyibilikayo kuba inezi zinzuzo zilandelayo

1. I-viscosity ye-polymer inokulawulwa ngokusebenzisa i-oxidants okanye i-peroxides kwinkqubo ye-extrusion, okanye ngokucheba ngomatshini i-extruder okanye ukulawula ukushisa okusebenzayo ukuphumeza ukuthotywa kwe-thermal, ukwenzela ukulawula i-viscosity yokunyibilika.

2. Ukuhanjiswa kobunzima bemolekyuli kunokulawulwa yinkqubo yelaphu elinyibilikayo elivuthelweyo elingaphothiweyo, elifuna ukuhanjiswa kobunzima bemolekyuli emxinwa kakhulu ukuze kuvele imicu efanayo ye-ultrafine. Ngokusebenzisa itekhnoloji entsha ye-catalytic efana ne-metallocene catalysts, iipolymers ezinesalathiso esinyibilikayo esiphakamileyo kunye nokusabalalisa ubunzima bemolekyuli kunokuveliswa.

3. Indawo ephezulu yokunyibilika yanele ukuchasana nobushushu bepolypropylene kwizicelo ezininzi zemveliso, kwaye inoluhlu olubanzi lwepropylene etyhidiweyo. Umda, ke ngoko, uluncedo kakhulu ekusetyenzweni kwebhondi ye-thermal eqhelekileyo kwitekhnoloji yelaphu elingalukwanga.

4. Kuyinzuzo ukuvelisa imicu ye-ultrafine. Ukuba i-viscosity ye-polypropylene inyibilika iphantsi kwaye ukusabalalisa ubunzima be-molecular kuncinci, kunokwenziwa kwimicu emihle kakhulu phantsi kokusetyenziswa kwamandla afanayo kunye neemeko zokwelula kwinkqubo yokunyibilika. Ke ngoko, idiameter yefayibha eqhelekileyo yepolypropylene inyibilika evuthelwa ilaphu elingalukwanga yi-2-5um, okanye nangakumbi.

5. Ngenxa yokusetyenziswa komzobo womoya oshushu ophezulu woxinzelelo kwinkqubo yokutshiza i-melt, kufuneka kusetyenziswe iipolymers ezinesalathisi esiphezulu se-melt, enenzuzo ekunyuseni imveliso kunye nokunciphisa ukusetyenziswa kwamandla. Okwangoku, i-chips ze-polypropylene ezisetyenziswa kakhulu zine-melt index ye-400-1200g / 10min kunye nokusabalalisa ubunzima be-molecular ukuvelisa i-ultrafine fibers kunye ne-linear density efunekayo.

6. Iitshiphusi zepolypropylene ezisetyenziswa kwimveliso evuthelweyo enyibilikayo kunye nokusetyenzwa kufuneka zibe nesalathiso sokunyibilika okuphezulu kunye nokufanayo, ukuhanjiswa kobunzima bemolekyuli emxinwa, iimpawu ezintle zokunyibilika ezinyibilikayo, kunye nomgangatho wetshiphu ofanayo kunye nozinzile wokuqinisekisa ukuzinza kwenkqubo yezinto ezinyibilikayo ezingeyolukiweyo.

Izilumkiso zokuveliswa kwelaphu elinyibilikayo

Kwinkqubo yokwenza ilaphu elinyibilikayo, kufuneka kuqatshelwe la manqaku alandelayo:

1. Ukukhethwa kwezinto eziphathekayo kufuneka kucoceke ngokwaneleyo: Njengoko ilaphu elinyibilikayo lifuna ukuthwala umphumo wokucoca, kuyimfuneko ukukhetha izinto ezicocekileyo ngokwaneleyo xa ukhetha izinto eziluhlaza. Ukuba kukho ukungcola okuninzi, kuya kuchaphazela ukusebenza kakuhle kokucoca kwelaphu elinyibilikayo.

2. Lawula iqondo lokushisa kunye noxinzelelo: Ubushushu bokusebenza kunye noxinzelelo kufuneka lubekwe ngokohlobo lwezinto eziluhlaza ukuze kuqinisekiswe ukusebenza kakuhle kokwenza ifayibha.

3. Ukuqinisekisa ucoceko kwindawo yokuvelisa: Njengoko ilaphu elinyibilikayo lisetyenziselwa ukuvelisa izixhobo ezikhuselayo ezifana nemaski, ucoceko kwindawo yokuvelisa ibaluleke kakhulu. Kuyimfuneko ukuqinisekisa ukucoceka kocweyo lwemveliso ukuphepha ukungcolisa iimveliso.

Dongguan Liansheng Non woven Technology Co., Ltd.yasekwa ngoMeyi 2020. Lishishini elikhulu lemveliso yelaphu elingalukiweyo elidibanisa uphando nophuhliso, imveliso, kunye neentengiso. Inokuvelisa imibala eyahlukeneyo ye-PP spunbond amalaphu angalukwanga kunye nobubanzi obungaphantsi kwe-3.2 yeemitha ukusuka kwi-9 grams ukuya kwi-300 grams.
