Utywala lwePVA Polyvinyl

I-Polyvinyl alcohol (PVA) yipolymer enyibilikayo emanzini ehlala imhlophe kwiflake, i-flocculent, okanye ifom yomgubo.

Ukunyibilika kwamanzi okugqwesileyo: inokunyibilika emanzini kumaqondo obushushu ahlukeneyo ukwenza isisombululo esicacileyo.

Ukubambelela okulungileyo: kunempembelelo enamandla yokudibanisa kwizinto ezahlukeneyo.

Ukwenziwa kwefilimu egqwesileyo: Ifilimu eyenziweyo inamandla aphezulu kunye nokuguquguquka.

Ukumelana nokunyibilika: Ukuya kumlinganiselo othile, inokumelana nokhukuliseko lwezinyibilikisi eziqhelekileyo.

I-Biocompatibility: Ngokuhambelanayo ayinayo ityhefu kwaye inobuhlobo kumzimba womntu kunye nokusingqongileyo.

Ishishini leempahla

Isetyenziswa njengesixhobo sokulinganisa i-warp ukuphucula amandla kunye nokunxiba ukuxhathisa kwemisonto.

Ukuprinta kunye nokudaya abancedisi, kunceda ukunamathela kwidayi kunye nokusabalalisa okufanayo.

Ishishini lamaphepha

I-agent yokulinganisa umphezulu wephepha ukunyusa amandla kunye nokumelana namanzi kwephepha.

I-pigment yokugqoka i-adhesive ukuphucula iimpawu zephepha elifakwe.

Intsimi yokuncamathelisa

I-Adhesive yomthi, iphepha, ifayibha kunye nezinye izinto.

Ishishini lokwakha

Izongezo zesamente zokuphucula iimpawu zesamente.

Intsimi yezonyango

Izinto ezikrwada ze-capsule yeziyobisi, izinto ezincedisayo zeyeza zamehlo.

Ngokuqhelekileyo ilungiselelwe yi-alcoholsis ye-polyvinyl acetate.

Ngokunyuka kwemfuno yezixhobo zokusebenza eziphezulu kumashishini ahlukeneyo, amathuba emarike ePVA abanzi. Iqhutywa kukuphuculwa kwamashishini emveli afana nelaphu kunye nokwenza iphepha, kunye nophuhliso lwamasimi asakhulayo afana ne-biomedicine kunye nezixhobo zombane, imfuno yayo yentengiso kulindeleke ukuba iqhubeke nokukhula.

Kuphephe ukufuma namaqondo obushushu aphezulu xa ugcina.

Xa uchithwa, ubushushu kunye nesantya sokuvuselela kufuneka kulawulwe ukuze kuqinisekiswe ukuchithwa okwaneleyo kwaye ukusebenza akuthinteki.

Khetha iimodeli ezifanelekileyo kunye neenkcukacha ngokweemfuno ezahlukeneyo zesicelo.

Ngokomzekelo, kwishishini le-textile, i-PVA ene-viscosity ethile kunye ne-alcoholic degree kufuneka ikhethwe ngokwezinto eziphathekayo kunye neemfuno zenkqubo yomsonto; Ekusetyenzisweni kwe-adhesives, ukuqulunqwa kunye nokusetyenziswa kwe-PVA kufuneka kulungiswe ngokobume be-adhesive.

Ukushwankathela, i-Polyvinyl alcohol idlala indima ebalulekileyo kwiinkalo ezininzi kunye neempawu zayo ezizodwa, inika inkxaso eqinile kuphuhliso lwamashishini anxulumeneyo.
