I-PVA isetyenziswa ngokuqhelekileyo njengeglue emhlophe okanye iglu yesikolo ngenxa yokusebenziseka kwayo ngokulula, i-non-toxicity, kunye nokunyibilika kwamanzi. Yenza ibhondi eyomeleleyo kwaye ebhetyebhetye enezixhobo ezahlukeneyo, kubandakanywa iphepha, ikhadibhodi, umthi, ilaphu, kunye neendawo ezivulekileyo.

b. Iglu yoMthi:

Iiglues zokhuni ezisekelwe kwi-PVA zithandwa kakhulu kwizicelo zokhuni zokudibanisa amaplanga, i-veneers kunye ne-laminates. Banikezela ngezibophelelo ezinamandla kunye nezizinzileyo, zixhathisa umswakama, kwaye kulula ukuhlambulula ngamanzi.

c. Craft Glue:

I-PVA isetyenziswa ngokubanzi kubugcisa kunye nobugcisa bokudibanisa iphepha, ilaphu, amagwebu, kunye nezinye izinto. Ifumaneka kwiindlela ezahlukeneyo, kubandakanywa iinguqulelo ezicacileyo kunye nezinemibala, ukuze zihambelane neeprojekthi ezahlukeneyo zobugcisa.

2. Umzi mveliso weMibhalo 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. IiTayipu 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. Ukusetyenziswa kwezamayeza:

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 zokujiya. 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.
