Ukusetyenziswa
I-Pentaerythritol isetyenziswa ngokubanzi kwishishini lokugquma ukuvelisa i-alkyd resins.Ezi resins ziyinxalenye ebalulekileyo yeengubo ezininzi, ezibonelela ngokuzinzileyo, ukubambelela kunye nokuxhathisa ukubola.Ukongeza, i-pentaerythritol ikwasetyenziswa ngokubanzi ekudibaneni kwezithambiso eziphambili ukubonelela ukusebenza okuphezulu kunye nokhuseleko oluhlala ixesha elide koomatshini kunye nezithuthi.
Ngaphaya koko, i-pentaerythritol sisithako esiphambili kwimveliso yeeplasticizers kunye ne-surfactants.Iiplastiki zeplastiki ziphucula ukuguquguquka kunye nokuqina kweeplastiki, zibenza zibe yinxalenye ebalulekileyo yezicelo ezahlukeneyo.Kwelinye icala, iipropathi ze-emulsifying kunye ne-foaming ze-surfactants zibalulekile kwaye zisetyenziswa kumashishini afana nokhathalelo lomntu, ukucoca kunye nezolimo.
Ngaphandle kwendima yayo kwizicelo ezahlukeneyo zemizi-mveliso, i-pentaerythritol ikwasetyenziswa ekudibaneni amachiza kunye neziqhushumbisi.Iimpawu zayo ezikhethekileyo zeekhemikhali zenza ukuba ibe yinto efanelekileyo kwimveliso yamachiza, inceda ukunyusa ukusebenza kunye nokuzinza kwezinto ezithile.Ukongezelela, iipropati ezinokutsha ze-pentaerythritol zenza ukuba ibe yinto ephambili ekwenzeni iziqhushumbisi, ukwandisa ukuzinza kunye namandla ezi zinto.
Ngokubanzi, i-pentaerythritol yikhompawundi exabiseke kakhulu yezinto eziphilayo ebonelela ngezicelo ezininzi kumashishini ahlukeneyo.Ukuguquguquka kwayo kunye nekhemikhali ekhethekileyo iyenza ibe sisithako esithandwayo ekwenziweni kweereyini ze-alkyd, izithambiso eziphambili, iiplastiki, ii-surfactants, amayeza kunye neziqhushumbisi.Ngefom ye-crystalline powder emhlophe, ifakwe ngokulula kwiinkqubo ezahlukeneyo, inika ukusebenza kakuhle kunye nokuthembeka.Themba i-pentaerythritol ukuphakamisa iimveliso zakho kunye nokuphucula ukusebenza kwazo.
