Kushandisa Zvigadzirwa
Seyakakosha kemikari mbishi zvinhu uye zvinonyungudutsa zvine mashandiro akanaka, dimethylformamide (DMF) inonyanya kushandiswa mu polyurethane, acrylic, mushonga, mishonga yezvipembenene, dhayi, zvemagetsi uye mamwe maindasitiri. Inonyanya kushandiswa mukugadzira yakanyorova yeganda rekugadzira sewachi uye kurapa mumiriri muindasitiri yepolyurethane. Muindasitiri yemishonga semushonga wekugadzira wepakati, unoshandiswa zvakanyanya mukugadzirwa kwedoxycycline, cortisone, sulfonamide zvinodhaka; Se solvent mu acrylic fiber indasitiri, inonyanya kushandiswa kuomesa kuruka kwe acrylic fiber. Muindasitiri yemishonga yezvipembenene yekubatanidza kwepamusoro kunyatsoshanda uye kuderera kwehuturu hwemishonga yezvipembenene; Muindasitiri yedhayi semugadziri wedhayi; In yemagetsi indasitiri sezvo tin plating zvikamu quenching uye redunhu bhodhi kuchenesa; Mamwe maindasitiri anosanganisira anotakura magasi ane njodzi, zvinonyungudutsa zvezvinodhaka crystallization, zvinonamira, nezvimwe.
Package Uye Kuchengeta
Packing: Iyo yekurongedza inogona kugadzirwa. nguva yekutumira inogona kuva negungwa, nemhepo, uye sampuli kana diki diki inogona kutumirwa neDHL, FEDEX, EMS uye TNT.
Kuchengeta: Chengetedza munzvimbo inotonhorera yakaoma, kure nechiedza chezuva
Mamiriro ekuchengetedza akachengeteka, kusanganisira chero kusawirirana
Yakaparadzaniswa kubva kune zvisingaenderane nezvinhu. Ona Kemikari Ngozi. Chengeta chigadziko chakavharwa zvakasimba munzvimbo yakaoma uye ine mhepo yakanaka. Magaba anenge akavhurwa anofanirwa kunyatsovharwa uye kugara akati twasu kudzivirira kudonha. Bata uye chengetedza pasi pegesi inert.

Chengetedzo yekubata zvakachengeteka
HAPANA mwoto wakavhurika, HAPANA pfarivari uye HAPANA kuputa. HAPANA kusangana neoxidizing agents. Pamusoro pe58°C inoshandisa yakavharwa sisitimu uye kufefetera. Kubata munzvimbo ine mhepo yakanaka. Pfeka zvipfeko zvinodzivirira zvakakodzera. Dzivisa kusangana neganda nemaziso. Dzivisa kuumbwa kweguruva uye aerosols. Shandisa midziyo isiri-sparking. Dzivirira moto unokonzerwa ne electrostatic discharge steam.
