PVC Grade HPMC

Ibakala lePVC iHPMC Hydroxypropyl Methylcellulose luhlobo lwepolymer olusetyenziswa kakhulu kunye nokusebenza okuphezulu phakathi kwazo zonke iintlobo zeselulosi. Isetyenziswa ngokubanzi kwiinkalo ezahlukeneyo zoshishino kunye nobomi bemihla ngemihla. Ibisoloko isaziwa njenge "MSG yamashishini".


IHydroxypropyl Methylcellulose (HPMC) ingasetyenziselwa ukwenziwa kweemveliso zepolyvinyl chloride (PVC), ngokukodwa kwi-PVC resin kunye ne-compound processing. Nangona kunjalo, kubalulekile ukucacisa ukuba i-HPMC ayilolungu le-PVC ngokwayo; kunokuba, inokuqeshwa njenge-lubricant yangaphandle okanye i-processing aid ngexesha lemveliso ye-PVC compounds kunye ne-resin.

    Indima ye-HPMC kwi-PVC Processing:

    inkcazelo2

    1. Ukuthanjiswa kwangaphakathi nangaphandle:

    I-HPMC inokusebenza njenge-arhente yokuthambisa kwi-PVC processing. Inceda ukuphucula iimpawu zokuhamba kwee-PVC compounds kunye nokunciphisa ukungqubuzana ngexesha le-extrusion kunye neenkqubo zokubumba. I-HPMC inokusebenza njenge-lubricant yangaphakathi nangaphandle, iphucula ukuqhubekeka ngokubanzi kwezinto zePVC.

    2. UkuPhuculwa kokuPhuculwa:

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

    3. UkuNcitshiswa kokusetyenziswa kwamandla:

    Iipropati zokuthambisa ze-HPMC zinokukhokelela ekunciphiseni ukusetyenziswa kwamandla ngexesha lokwenziwa kwePVC. Oku akuncedi nje kuphela kwindalo esingqongileyo kodwa kukwabiza imali eninzi kubavelisi.

    4. Uncedo ekuthinteleni ukuncamathela:

    Kwiinkqubo ezibandakanya ukufudumeza kunye nokubunjwa kwe-PVC, njenge-extrusion kunye ne-injection molding, i-HPMC inceda ukunqanda ukunamathela okanye ukunamathela kwizinto ze-PVC kwizixhobo zokusebenza.

    Ukusetyenziswa kwePVC Grade HPMC:

    inkcazelo2

    I-PVC yeBanga le-HPMC isetyenziswa ikakhulu kushishino lwePVC kwaye inokusetyenziswa kwiinkqubo ezahlukeneyo zePVC, kubandakanya:

    1. PVC Extrusion:

    I-HPMC ingasetyenziswa kwi-extrusion yeeprofayili ze-PVC, imibhobho, kunye nezinye iimveliso, apho inceda ekuphuculeni iipropati zokuhamba kunye nokunciphisa ukusetyenziswa kwamandla.

    2. Ukubunjwa kwesitofu sePVC:

    Isitofu sokubumba iimveliso ze-PVC, ezifana nokufakwa kunye namacandelo, banokuzuza ekusebenziseni i-HPMC ukunqanda ukunamathela kunye nokuphucula ukukhutshwa komngundo.

    3. Ukudibanisa iPVC:

    Kwi-PVC yokudibanisa, apho izongezelelo ezahlukeneyo kunye nezihluzi zidityaniswe ne-PVC resin, i-HPMC inokusebenza njengoncedo lokucubungula ukuququzelela ukusasazwa okufanayo kunye nokuphucula ukuqhubekeka.

    4. Ikhalenda yePVC:

    I-HPMC ingaqeshwa kwiinkqubo ze-PVC ze-calendering zokuveliswa kwamaphepha kunye neefilimu, apho kunceda ukunciphisa ukungqubuzana kunye nokuphucula umgangatho wemveliso yokugqibela.

    Izinto ezilungileyo zokusebenzisa iBanga lePVC leHPMC:

    inkcazelo2

    - Ukuphuculwa kwepropathi kunye nokuhamba kweempawu zePVC compounds.
