• PVA 2488, ine emulsifying zvivakwa, inogona kushandiswa mukugadzira emulsion.

Zvinotarisirwa:

1. Magadzirirwo Akananga:

• Sarudzo yegiredhi rePVA, kusanganisira PVA 2488, zvinoenderana nezvinodiwa chaizvo zvekushandiswa kwakarongwa. Madhigirii akasiyana ehydrolysis uye mamorekuru uremu anopa misiyano mukuita.

2. Kugarisana:

• PVA 2488 inowanzosarudzwa zvichienderana nekuenderana kwayo nezvimwe zvinongedzo mukugadzira uye kugona kwayo kusangana neinodiwa maitiro ekuita.

3. Supplier Recommenditions:

• Kushanda padhuze nePVA vatengesi nevagadziri kwakakosha kuti uwane gwara rekushandisa kwakaringana kwePVA 2488 mumagadzirirwo akasiyana. Vatengesi vanogona kupa ruzivo mukugadzirisa mazano uye kuenderana nezvimwe zvinowedzera.

Muchidimbu, PVA 2488 igiredhi chairo rePolyvinyl Doro rine hunhu hwakasiyana hunoita kuti ive yakakodzera kune akasiyana maapplication, kunyanya mune anonamira, machira, mapeji ekuputira, zvekuvakisa, nezvimwe. Kana uchifunga nezvechirevo chechinyorwa kana mashandisirwo, kupa rumwe ruzivo kunogonesa mhinduro chaiyo.
