Kushandiswa
Pentaerythritol inonyanya kushandiswa muindasitiri yekuputira. Inogona kushandiswa kugadzira alkyd resin coatings, iyo inogona kuvandudza kuomarara, kupenya uye kugara kwenguva refu kwefirimu rekuputira. Inoshandiswawo sechinhu chisina kubikwa che rosin esters chinodiwa pakupenda, mavarnish uye inki dzekudhinda, uye inogona kushandiswa kugadzira mafuta ekuomesa, machira anopfungaira uye mafuta ekufambisa ndege. Pamusoro pezvo, inoshandiswawo mukugadzira mishonga, mishonga yezvipembenene nezvimwe zvigadzirwa. Molekyuru yepentaerythritol ine mapoka mana akaenzana ehydroxymethyl uye ine mwero wepamusoro wekuenzana. Nokudaro, inowanzoshandiswa sechinhu chisina kubikwa chekugadzira ma polyfunctional compounds. Nitrification yayo inogona kugadzira pentaerythritol tetranitrate, inova kuputika kune simba; esterification inogona kuwana pentaerythritol triacrylate, iyo inoshandiswa se coat. Inogona zvakare kushandiswa sechinodzivirira murazvo kune zvinonamatira. Kana yakabatanidzwa ne ammonium polyphosphate, chinhu chinodzivisa murazvo chinobuda mukati chinogona kuwanikwa. Inoshandiswawo semushonga wekubatanidza polyurethane kuti ipe cheni dzakagadzirwa ne polyurethane.
Kurongedza uye Kutumira
Kurongedza: 25/kg,Mabhegi epurasitiki akarukwa kana mapepa ekugadzira kana zvichienderana nezvinodiwa nevatengi.
Kutumirwa: ndekwemakemikari akajairika uye kunogona kutumirwa nechitima, gungwa nemhepo.
Chengeta uye chengeta
Nguva yesherufu: Mwedzi makumi maviri nemana kubva pazuva rekugadzirwa kwayo, yakachengetwa munzvimbo inotonhorera yakaoma isina chiedza chezuva, mvura.
Imba yekuchengetera zvinhu ine mhepo, Inoomesa zvinhu zvishoma, Yakaparadzaniswa nezvinokonzera makemikari, maasidhi.
