Polyvinyl cawv rau cov kua nplaum thiab lwm yam kev siv

Polyvinyl Cawv (PVA) yog ib qho khoom siv polymer nrog ntau yam kev siv, nrog rau nws siv los ua cov kua nplaum thiab ntau yam kev lag luam. Nov yog cov ntsiab lus ntawm Polyvinyl Cawv rau cov kua nplaum thiab lwm yam kev siv:

1. Glue thiab Adhesives:

ib. PVA kua nplaum:

PVA feem ntau yog siv los ua cov kua nplaum dawb lossis cov kua nplaum hauv tsev kawm ntawv vim nws yooj yim siv, tsis muaj tshuaj lom, thiab dej solubility. Nws tsim ib daim ntawv cog lus muaj zog thiab hloov tau nrog ntau yam ntaub ntawv, suav nrog ntawv, duab los qhia, ntoo, ntaub, thiab qhov ntxeem tau.

b. Ntoo kua nplaum:

PVA-raws li ntoo nplaum yog nrov hauv kev siv ntoo rau kev sib txuas ntoo, veneers, thiab laminates. Lawv muab cov khoom ruaj khov thiab ruaj khov, tiv taus cov dej noo, thiab yooj yim los ntxuav nrog dej.

c. Craft Glue:

PVA yog siv dav hauv kev kos duab thiab khoom siv tes ua rau cov ntawv sib txuas, ntaub, ua npuas ncauj, thiab lwm yam ntaub ntawv. Nws muaj nyob rau hauv ntau yam formulations, nrog rau cov ntshiab thiab xim versions, kom haum cov khoom siv tes ua sib txawv.

2. Textile thiab Ntawv Industries:

ib. Textile Sizing:

PVA yog siv los ua tus neeg sawv cev hauv kev tsim textile los txhim kho lub zog, smoothness, thiab tuav cov khoom ntawm yarns thiab fabrics. Nws tsim ib zaj duab xis rau saum npoo ntawm fibers, muab lubrication thiab txo kev sib txhuam thaum lub sij hawm weaving thiab ua.

b. Ntawv Txheej:

PVA yog ua hauj lwm nyob rau hauv daim ntawv txheej formulations los txhim kho nto smoothness, brightness, thiab printability. Nws tsim ib txheej txheej txheej ntawm daim ntawv, txhim kho number case adhesion thiab txo tus number case nqus.

3. Ntim:

ib. Adhesive Tapes:

PVA-raws li adhesives yog siv rau hauv kev tsim cov nplaum nplaum rau ntim, sealing, thiab daim ntawv thov. Lawv muab lub zog pib tack thiab adhesion rau ntau yam substrates, nrog rau cov duab los qhia, yas, thiab hlau.

b. Carton Sealing:

PVA adhesives yog siv rau kev sib khi cov thawv ntawv, thawv, thiab cov khoom ntim. Lawv muab cov khoom sib txuas ruaj khov thiab sib khi, ua kom muaj kev ruaj ntseg thiab tamper-pom zoo ntim cov kev daws teeb meem.

4. Khoom siv:

ib. Gypsum khoom:

PVA yog ntxiv rau cov khoom siv gypsum xws li kev sib koom ua ke, plasters, thiab cov nplaum phab ntsa. Nws txhim kho kev ua haujlwm, adhesion, thiab tawg tsis kam ntawm gypsum formulations.

b. Cov khoom siv cementitious:

PVA-raws li additives yog siv nyob rau hauv cov ntaub ntawv cementitious xws li mortars, renders, thiab pobzeb adhesives los txhim kho kev ua hauj lwm, adhesion, thiab durability. Lawv txhim kho cov dej tuav, sag tsis kam, thiab kev sib khi lub zog hauv kev tsim kho.

5. Cov Khoom Siv Kho Tus Kheej:

ib. Tshuaj pleev ib ce:

PVA derivatives yog siv rau hauv cov tshuaj pleev ib ce thiab cov khoom tu tus kheej xws li cov plaub hau styling gels, cream, thiab tshuaj pleev ib ce. Lawv ua raws li thickeners, zaj duab xis qub, thiab stabilizers, muab kev ntxhib los mos, viscosity, thiab stability rau formulations.

b. Contact Lens Solutions:

PVA yog siv nyob rau hauv kev sib cuag lo ntsiab muag raws li ib tug lubricating tus neeg saib xyuas thiab ntub dej. Nws pab tswj kom muaj dej noo thiab kev nplij siab ntawm qhov chaw ntawm lub ntsej muag, txo kev sib txhuam thiab khaus thaum hnav.

6. Kev siv tshuaj:

ib. Tablet Coatings:

PVA-raws li txheej yog siv nyob rau hauv cov tshuaj ntsiav tshuaj formulations muab enteric, sustained, los yog ncua sij hawm-tso khoom. Lawv tiv thaiv cov khoom xyaw nquag los ntawm degradation, tswj cov tshuaj tso tawm, thiab txhim kho kev ua raws li tus neeg mob.

b. Excipients:

PVA derivatives yog siv los ua excipients nyob rau hauv cov tshuaj formulations rau lawv binding, disintegrating, thiab thickening zog. Lawv txhim khu cov ntsiav tshuaj, stability, thiab bioavailability nyob rau hauv cov ntaub ntawv ntau npaum li cas.

Xaus:

Polyvinyl Cawv (PVA) yog cov khoom siv ntau yam polymer nrog ntau yam kev siv hauv cov kua nplaum thiab cov nplaum nplaum, nrog rau ntau yam kev lag luam xws li textiles, ntawv, ntim, kev tsim kho, kev tu tus kheej, thiab tshuaj. Nws cov khoom tshwj xeeb, suav nrog dej solubility, adhesion, zaj duab xis-tsim, thiab biocompatibility, ua rau nws muaj txiaj ntsig rau ntau daim ntawv thov thoob plaws ntau qhov chaw. Raws li qhov tshwm sim, PVA tseem yog cov khoom siv dav siv thiab tseem ceeb hauv ntau cov khoom lag luam thiab cov neeg siv khoom.
