Ibanga le-PVC le-HPMC

I-HPMC Hydroxypropyl Methylcellulose yodidi lwe-PVC yintlobo ye-polymer enokusetyenziswa kakhulu kwaye isebenza kakhulu phakathi kwazo zonke iintlobo ze-cellulose. Isetyenziswa kakhulu kwiinkalo ezahlukeneyo zoshishino nakubomi bemihla ngemihla. Ibisoloko isaziwa ngokuba yi-"industrial MSG".


IHydroxypropyl Methylcellulose (HPMC) ingasetyenziswa ekwenzeni iimveliso zepolyvinyl chloride (PVC), ngakumbi kwi-resin yePVC kunye nokucubungula izinto ezidityanisiweyo. Nangona kunjalo, kubalulekile ukucacisa ukuba iHPMC ayilolungu lePVC ngokwayo; endaweni yoko, ingasetyenziswa njenge-lubricant yangaphandle okanye uncedo lokucubungula ngexesha lokuvelisa izinto ezidityanisiweyo zePVC kunye ne-resin.

    inkcazo2

    1. Ukuthambisa Ngaphakathi Nangaphandle:

    I-HPMC ingasebenza njenge-arhente yokuthambisa xa kusetyenzwa nge-PVC. Inceda ekuphuculeni iipropati zokuhamba kweekhompawundi ze-PVC kwaye inciphise ukungqubana ngexesha leenkqubo zokukhupha kunye nokubumba. I-HPMC ingasebenza njenge-lubricant yangaphakathi neyangaphandle, iphucula ukuqhubekeka kwezixhobo ze-PVC.

    2. Ukuphuculwa kokuSebenza:

    Ukongezwa kwe-HPMC kwiikhompawundi ze-PVC kunye ne-resin kunokuphucula ukusebenziseka kwazo, okwenza kube lula ukwenza nokubumba iimveliso ze-PVC. Oku kubaluleke kakhulu kumashishini apho ukubumba kunye nokukhupha ngokuchanekileyo kubaluleke kakhulu.

    3. Ukusetyenziswa kwamandla okuncitshisiweyo:

    Iimpawu zokuthambisa ze-HPMC zinokubangela ukusetyenziswa kwamandla okunciphileyo ngexesha lokucubungula i-PVC. Oku akuncedi nje kuphela kwindalo esingqongileyo kodwa kukwaluncedo nakwixabiso elifanelekileyo kubavelisi.

    4. Uncedo ekuthinteleni ukunamathela:

    Kwiinkqubo ezibandakanya ukufudumeza nokubunjwa kwePVC, ezinje ngokuphuma kunye nokubumba ngenaliti, iHPMC inceda ekuthinteleni ukunamathela okanye ukunamathela kwezinto zePVC kwizixhobo zokucubungula.

    Usetyenziso lwe-PVC yeBanga le-HPMC:

    inkcazo2

    I-HPMC ye-PVC yebanga isetyenziswa kakhulu kwishishini le-PVC kwaye ingasetyenziswa kwizicelo ezahlukeneyo zokucubungula i-PVC, kuquka:

    1. Ukwandiswa kwePVC:

    I-HPMC ingasetyenziswa ekukhupheni iiprofayili ze-PVC, imibhobho, kunye nezinye iimveliso, apho inceda ekuphuculeni iimpawu zokuhamba kwamanzi kunye nokunciphisa ukusetyenziswa kwamandla.

    2. Ukubumba inaliti yePVC:

    Ukufumba kweemveliso zePVC ngenaliti, ezifana nezixhobo kunye nezinto ezisetyenziswayo, kunokuzuza ekusebenziseni i-HPMC ukuthintela ukunamathela nokuphucula ukukhululwa kwesikhunta.

    3. Ukudibanisa iPVC:

    Kwi-PVC compounding, apho izongezo ezahlukeneyo kunye nezizalisi zidityaniswe ne-PVC resin, i-HPMC inokusebenza njengoncedo lokucubungula ukuze kube lula ukusasazwa okufanayo kunye nokuphucula ukucutshungulwa.

    4. Ukwenziwa kwekhalenda yePVC:

    I-HPMC ingasetyenziswa kwiinkqubo ze-PVC zokulinganisa ii-calender ukuvelisa amaphepha kunye neefilimu, apho inceda ekunciphiseni ukungqubana nokuphucula umgangatho wemveliso yokugqibela.

    Iingenelo zokusebenzisa i-PVC Grade HPMC:

    inkcazo2

    - Ukuphuculwa kweendlela zokucubungula kunye neempawu zokuhamba kwamanzi kwiikhompawundi zePVC.
    - Ukuphucula ukusebenza kwe-extrusion kunye nokubumba.
    - Ukusetyenziswa kwamandla okuncitshisiweyo ngexesha lokucubungula.
