2. Imizi-mveliso yeMibhalo kunye nePhepha:

a.Ubungakanani beLaphu:

I-PVA isetyenziswa njenge-ejenti yokulinganisa kwimveliso yelaphu ukuphucula ukomelela, ukuguda, kunye nokuphatha iimpawu zemisonto kunye namalaphu.Yenza ifilimu kumphezulu wemicu, ibonelela ngokuthambisa kunye nokunciphisa ukukhuhlana ngexesha lokuluka kunye nokucubungula.

b.Ukugquma ngePhepha:

I-PVA isetyenziswa kwimixube yokugquma iphepha ukomeleza ukuguda komphezulu, ukuqaqamba, kunye nokuprintwa.Yenza umaleko wokugquma ofanayo kwimigangatho yephepha, iphucula ukuncamathela kwe-inki kunye nokunciphisa ukufunxwa kwe-inki.

3. Ukupakishwa:

a.Iiteyiphu ezincamathelayo:

Izinto zokuncamathelisa ezisekelwe kwi-PVA zisetyenziselwa ukwenziwa kweeteyiphu zokuncamathelisa ukupakishwa, ukutywina, kunye nokufakwa kweelebhile.Babonelela ngobuchule bokuqala obuqinileyo kunye nokubambelela kwii-substrates ezahlukeneyo, kubandakanya ikhadibhodi, iplastiki kunye nentsimbi.

b.Ukutywinwa kweKhathoni:

Izinto zokuncamathelisa zePVA zisetyenziselwa ukutywina iibhokisi zekhadibhodi, iibhokisi, kunye nezinto zokupakisha.Banikezela ngeempawu ezithembekileyo zokudibanisa kunye nokutywinwa, ukuqinisekisa izisombululo zokupakisha ezikhuselekileyo nezicacileyo.

4. Izinto zokwakha:

a.Iimveliso zeGypsum:

I-PVA yongezwa kwiimveliso ezisekelwe kwi-gypsum ezifana neekhompawundi ezidibeneyo, i-plasters, kunye ne-wallboard adhesives.Iphucula ukusebenza, ukunamathela, kunye nokumelana nokuqhekeka kwe-gypsum formulations.

b.Iimveliso zesamente:

Izongezo ezisekelwe kwi-PVA zisetyenziselwa izinto zesamente ezifana nodaka, unikezelo, kunye ne-adhesives yethayile ukuphucula ukusebenza, ukubambelela kunye nokuqina.Baphucula ukugcinwa kwamanzi, ukunganyangeki, kunye namandla ebhondi kwizicelo zokwakha.

5. IiMveliso zokuKhathalela umntu:

a.Izithambiso:

Izinto eziphuma kwi-PVA zisetyenziswa kwizinto zokuthambisa kunye neemveliso zokhathalelo lomntu ezifana neegels zokulungisa iinwele, iikhrimu, kunye nezinto zokuthambisa.Basebenza njengama-thickeners, abaqulunqi befilimu, kunye nezizinzi, banikezela ukuthungwa, i-viscosity, kunye nokuzinza kwiifomyula.

b.Qhagamshelana neLens Solutions:

I-PVA isetyenziswe kwizisombululo ze-lens zoqhagamshelwano njenge-agent yokuthambisa kunye ne-agent yokumanzisa.Inceda ukugcina umswakama kunye nokuthuthuzela kumphezulu wee-lens zoqhagamshelwano, ukunciphisa ukungqubuzana kunye nokucaphuka ngexesha lokugqoka.

6. Usetyenziso lwezamayeza:

a.Iingubo zeCwecwe:

Iingubo ezisekelwe kwi-PVA zisetyenziselwa ukuqulunqa iipilisi ze-pharmaceutical ukubonelela nge-enteric, ezinzileyo, okanye iipropati zokulibaziseka.Zikhusela izithako ezisebenzayo ekuthotyweni, ukulawula ukukhutshwa kweziyobisi, kunye nokuphucula ukuthotyelwa kwesigulane.

b.Abancedisi:

I-PVA derivatives isetyenziswa njengezinto ezincedisayo kwimixube yoxubo lokubopha, ukuqhekeka, kunye neempawu ezityebisayo.Baphucula iipropathi zethebhulethi, uzinzo, kunye ne-bioavailability kwiifom zedosi eqinileyo.

Isiphelo:

I-Polyvinyl Alcohol (PVA) i-polymer eguquguqukayo kunye noluhlu olubanzi lwezicelo kwi-glue kunye ne-adhesive formulations, kunye nakwamanye amashishini ahlukeneyo afana neendwangu, iphepha, ukupakisha, ukwakhiwa, ukunyamekelwa komntu, kunye namayeza.Iimpawu zayo ezikhethekileyo, ezibandakanya ukunyibilika kwamanzi, ukunamathela, ukwenza ifilimu, kunye ne-biocompatibility, kuyenza ixabiseke kwizicelo ezahlukeneyo kumacandelo ahlukeneyo.Ngenxa yoko, i-PVA iyaqhubeka ukuba yinto esetyenziswa ngokubanzi kwaye iyimfuneko kwimveliso emininzi kunye neemveliso zabathengi.
