Polyvinyl Alcohol Bakeng sa Sekhomaretsi le Lisebelisoa tse ling

Polyvinyl Alcohol (PVA) ke polima e feto-fetohang e nang le mefuta e mengata ea ts'ebeliso, ho kenyeletsoa ts'ebeliso ea eona joalo ka sekhomaretsi le liindastering tse ling tse fapaneng.Mona ke kakaretso ea Alcohol ea Polyvinyl bakeng sa sekhomaretsi le lits'ebeliso tse ling tsa eona:

1. Sekhomaretsi le Likhomaretsi:

a.Sekhomaretsi sa PVA:

PVA e atisa ho sebelisoa e le sekhomaretsi se sesoeu kapa sekhomaretsi sa sekolo ka lebaka la ho se sebelise habonolo, ho se chefo, le ho qhibiliha ha metsi.E theha maqhama a matla le a tenyetsehang a nang le lisebelisoa tse fapaneng, ho kenyeletsoa pampiri, khateboto, lehong, lesela, le libaka tse nang le masoba.

b.Sekhomaretsi sa Lehong:

Likhomaretsi tsa lehong tse thehiloeng ho PVA li ratoa haholo ha ho etsoa mapolanka bakeng sa ho kopanya manonyeletso a lehong, li-veneers le laminate.Li fana ka litlamo tse matla le tse tšoarellang, li hanela mongobo, 'me li bonolo ho li hloekisa ka metsi.

c.Craft Glue:

PVA e sebelisoa haholo ho tsa bonono le mesebetsi ea matsoho bakeng sa ho kopanya pampiri, lesela, foam le lisebelisoa tse ling.E fumaneha ka mefuta e fapaneng, ho kenyelletsa le liphetolelo tse hlakileng le tse mebala, ho lumellana le merero e fapaneng ea mesebetsi ea matsoho.

2. Liindasteri tsa Textile le Pampiri:

a.Tekanyo ea Lesela:

PVA e sebelisoa e le sesebelisoa sa boholo tlhahisong ea masela ho ntlafatsa matla, boreleli le thepa ea ho sebetsana le likhoele le masela.E etsa filimi holim'a likhoele, e fana ka lubrication le ho fokotsa likhohlano nakong ea ho loha le ho sebetsa.

b.Ho roala ka pampiri:

PVA e sebelisoa ka mokhoa oa ho roala pampiri ho ntlafatsa boreleli, ho khanya le ho hatisoa.E etsa lesela le ts'oanang la ho roala holim'a pampiri, e ntlafatsa ho khomarela enke le ho fokotsa ho monya ha enke.

3. Sephutheloana:

a.Litheipi tse Khomaretsang:

Likhomaretsi tse thehiloeng ho PVA li sebelisoa ha ho etsoa litheipi tsa sekhomaretsi bakeng sa ho paka, ho tiisa le ho ngola lits'ebetso.Ba fana ka tack e matla ea pele le ho khomarela li-substrates tse fapaneng, ho kenyeletsoa karete, polasetiki le tšepe.

b.Ho Tiisa Carton:

Likhomaretsi tsa PVA li sebelisetsoa ho tiisa mabokose a karete, mabokose le thepa ea ho paka.Ba fana ka thepa e ka tšeptjoang ea ho kopanya le ho tiisa, ho netefatsa hore ho na le tharollo e sireletsehileng le e hlakileng ea ho paka.

4. Lisebelisoa tsa Kaho:

a.Lihlahisoa tsa Gypsum:

PVA e eketsoa lihlahisoa tse thehiloeng ho gypsum joalo ka metsoako e kopaneng, lipolasetere le likhomaretsi tsa leboteng.E ntlafatsa ho sebetsa, ho khomarela, le ho hanyetsa maqheka a metsoako ea gypsum.

b.Lihlahisoa tsa Cementitious:

Li-additives tse thehiloeng ho PVA li sebelisoa ka thepa ea samente e kang seretse, li-renders le li-adhesives tsa lithaele ho matlafatsa ts'ebetso, ho khomarela le ho tšoarella.Ba ntlafatsa ho boloka metsi, ho hanyetsa ho fokotseha, le matla a bond lits'ebetsong tsa kaho.

5. Lihlahisoa tsa Tlhokomelo ea Motho:

a.Litlolo:

Li-derivatives tsa PVA li sebelisoa ho litlolo le lihlahisoa tsa tlhokomelo ea motho joalo ka li-gel tsa setaele sa moriri, litlolo le litlolo.Li sebetsa e le li-thickeners, baetsi ba lifilimi, le li-stabilizers, li fana ka sebopeho, viscosity, le botsitso ho libopeho.

b.Ikopanye le Litharollo tsa Lense:

PVA e sebelisoa litharollong tsa lense ea ho ikopanya joalo ka ntho e tlotsang le e kenyang metsi.E thusa ho boloka mongobo le matšeliso holim'a lilense tsa ho kopana, ho fokotsa ho ferekana le ho halefa nakong ea ho apara.

6. Lisebelisoa tsa Meriana:

a.Liaparo tsa Letlapa:

Liaparo tse thehiloeng ho PVA li sebelisoa mefuteng ea lipilisi tsa meriana ho fana ka thepa ea enteric, e tsitsitseng, kapa e liehang ho lokolloa.Li sireletsa metsoako e sebetsang ho tloha ho senyeha, ho laola ho lokolloa ha lithethefatsi, le ho ntlafatsa ho lumellana le mokuli.

b.Bathusi:

Li-derivatives tsa PVA li sebelisoa e le li-excipient mefuteng ea meriana bakeng sa thepa ea tsona e tlamang, ea ho qhaqhoa le e teteaneng.Li ntlafatsa thepa ea letlapa, botsitso, le bioavailability ka mefuta e tiileng ea litekanyetso.

Qetello:

Polyvinyl Alcohol (PVA) ke polima e feto-fetohang e nang le mefuta e mengata e fapaneng ea likopo tsa sekhomaretsi le sekhomaretsi, hammoho le liindastering tse ling tse fapaneng joalo ka masela, pampiri, ho paka, kaho, tlhokomelo ea motho le meriana.Thepa ea eona e ikhethang, ho kenyelletsa ho qhibiliha ha metsi, ho khomarela, ho etsa lifilimi, le biocompatibility, e etsa hore e be ea bohlokoa bakeng sa lits'ebetso tse fapaneng makaleng a fapaneng.Ka lebaka leo, PVA e ntse e tsoela pele ho ba sesebelisoa se sebelisoang haholo le sa bohlokoa haholo lihlahisoa tse ngata tsa indasteri le tsa bareki.
