Polyvinyl Utywala PVA 2488

Utywala bePolyvinyl(PVA) 2488 libakala elithile le-PVA, kwaye igama lamanani lihlala libonisa iinkcukacha ezithile okanye iimpawu zeli bakala lithile. I-PVA yipolymer yokwenziwa eveliswe yi-hydrolysis ye-polyvinyl acetate. I-PVA 2488, njengamanye amabakala e-PVA, iyaziwa ngokuba yi-solubility yamanzi kunye neempawu zokwenza ifilimu. Nazi ezinye iimpawu eziphambili kunye nezicelo eziqhelekileyo ezinxulumene nePVA 2488:

Iimpawu zePVA 2488:

1. Isidanga seHydrolysis:

• Iqondo le-hydrolysis kwi-PVA 2488 libhekiselele kwinqanaba apho i-polyvinyl acetate ifakwe i-hydrolyzed ukwenza i-polyvinyl alcohol. Amabakala ahlukeneyo e-PVA anokuba namanqanaba ahlukeneyo e-hydrolysis, echaphazela iipropati zabo.

2. Ubunzima beMolekyuli:

• I-PVA 2488 inokuba nobunzima obuthile bemolekyuli, echaphazela i-viscosity yayo kunye nobuchule bokwenza ifilimu.

3. Ifomu yoMzimba:

• I-PVA 2488 idla ngokufumaneka ngohlobo lomgubo omhlophe ukuya kumhlophe.

Usetyenziso oluqhelekileyo:

1. Izinto ezincamathelayo:

• I-PVA 2488 isoloko isetyenziswa njengenxalenye ephambili kwiintlobo ezahlukeneyo zokuncamathelisa, kubandakanywa ukunamathiswa komthi kunye nokunamathiswa kwephepha. Inika amandla okudibanisa okulungileyo kunye nokuguquguquka.

2. Ubungakanani beLaphu:

• Kushishino lwamalaphu, iPVA 2488 ingasetyenziselwa ukwenza ubungakanani bemilinganiselo ukuphucula amandla kunye nokuphatha iimpawu zemisonto.

3. Iingubo zePhepha:

• I-PVA 2488 ingasetyenziswa kwishishini lephepha lokwaleka, ukuphucula izakhiwo ezingaphezulu kunye nokuprintwa kwephepha.

4. Izinto zokwakha:

• I-PVA 2488 inokufumana izicelo kwishishini lokwakha, ngokukodwa njenge-additive in formulations ye-samente ukuphucula ukubambelela kunye nokuguquguquka.

5. Ukupakishwa:

• Iifilimu ze-PVA, ezibandakanya ezo zisekelwe kwi-PVA 2488, zisetyenziselwa izicelo zokupakisha ezinamanzi.

6. Izicelo zonyango:

• I-PVA, ngokubanzi, isetyenziswe kwizicelo zonyango, kubandakanywa nokuveliswa kweeglavu zotyando kunye nenxalenye yokulawulwa kokukhutshwa kweyeza.

7. Izifanisi:

• I-PVA 2488, eneempawu zayo zokumisela, inokuqeshwa kwimveliso yee-emulsions.

Iingqwalasela:

1. IiNgcaciso zoLungiso:

• Ukukhethwa kwebakala le-PVA, kuquka i-PVA 2488, kuxhomekeke kwiimfuno ezithile zesicelo esijoliswe kuyo. Iidigri ezahlukeneyo ze-hydrolysis kunye nobunzima bemolekyuli zibonelela ngeenguqu ekusebenzeni.

2. Ukuhambelana:

• I-PVA 2488 isoloko ikhethwa ngokusekelwe ekusebenzisaneni kwayo nezinye izithako ekuqulunqweni kunye nokukwazi kwayo ukuhlangabezana nemilinganiselo yokusebenza efunekayo.

3. Iingcebiso zababoneleli:

• Ukusebenza ngokusondeleyo nabanikezeli be-PVA kunye nabavelisi kubalulekile ekufumaneni isikhokelo ekusetyenzisweni ngokupheleleyo kwePVA 2488 kwiindlela ezahlukeneyo zokuqulunqa. Ababoneleli banokunika ingqiqo kwizicwangciso zokuqulunqa kunye nokuhambelana nezinye izongezo.

Isishwankathelo, i-PVA 2488 ibakala elithile le-Polyvinyl Alcohol eneempawu ezahlukileyo ezenza ukuba zilungele izicelo ezahlukeneyo, ngokukodwa kwi-adhesives, i-textiles, i-coatings yamaphepha, izinto zokwakha, kunye nokunye. Ukuba unomxholo okanye isicelo esithile engqondweni, ukunika iinkcukacha ezongezelelweyo kuya kwenza impendulo echanekileyo ngakumbi.
