Fluorescent whitening agentyakagara ichiita basa re "monosodium glutamate" mukugadzirwa kwepurasitiki.Kuwedzerwa kwezviuru gumi zvishoma zvinogona kuchena uye kupenya zvigadzirwa zvepurasitiki nekuvandudza kutaridzika kwepurasitiki.
Kune nzira dzakawanda dzekuwedzera maajenti ekuchena, asi nzira dzekushandisa dzadzo dzakakamurwa muzvikamu zvitatu: kuchena kwakaoma, kuchena kwemvura uye masterbatch whitening.
Dry whitening
Plastic drying whitening ndeyekuwedzera imwe huwandu hwefluorescent whitening agent hupfu hwakaoma zvakananga kune substrate yepurasitiki isati yaumbwa, sanganisa nepurasitiki substrate kutanga, uye extrude musanganiswa kana extruder yasvika pakunyungudika kwepurasitiki.Nyunguduka mukati sikuruu kuita kuti purasitiki ichenese mumiriri igovaniswa mukunyunguduka, uye pakupedzisira ita granulation kana compression molding.
Dry process plastic whitening agent inonyanya kushandiswa kuumba jekiseni kuchena kweiyo yakaoma PVC, polyethylene, polypropylene, ABS uye mamwe thermoplastic resins.Fluorescent whitening agents anoshandiswa mumaomese ekuchenesa maajenti akachipa, asi ane zvakaipira kupararira kweguruva uye kusvibiswa kwezvakatipoteredza.
Chiitiko chekuchenesa
Kuti uvandudze kuparadzira mhedzisiro yekunyorova kuchena, dzimwe nguva zvinodikanwa kuwedzera imwe huwandu hwebhainda kune yepurasitiki chena mumiriri, kuitira kuti iyo yepurasitiki yekuchena mumiriri igone kunamatira zviri nani pamusoro pechinhu, kuitira kuderedza guruva rayo. kubhururuka uye kusvibiswa.
Iyo yepurasitiki inopenya inogonawo kuparadzirwa mumhinduro yekubatsira uye yakawedzerwa mumabheti nenzira yekubatsira kupararira.Semuenzaniso, inogona kushandiswa mune yakapfava polyvinyl chloride (PVC), iyo inogona kuumbwa kuita 10% phthalic acid.Mushure meiyo dioctyl ester plasticizer mhinduro, yakawedzerwa mumabhechi.
Mukunyorova kuchena, theplastiki whitening agentis a slurry yakapararira zvakanaka, iyo ine dhizaini yekunamira nekuti isiri-volatile organic solvent inosanganiswa muplasticizer.Hony Chemical inowanzokurudzira iyi nzira yekuchena yePVC yakapfava.
Masterbatch whitening
Parizvino, kushandiswa kwe "masterbatch" mumapurasitiki kwave nzira yakakosha yemavara epurasitiki.Paunenge uchishandisa ruvara masterbatch, chero bedzi iyo colorbatch uye resin yakasanganiswa zvakaenzana muchiyero, inogona kushandiswa zvakananga kuumba zvigadzirwa zvepurasitiki.
Kukurukurirana kuduku kunongoda kuitwa nemaoko.Panyaya yehuwandu hwekugadzirisa, kuitira kuti uve nechokwadi chekupararira kwe masterbatch, mechanical kumutsa inogona kushandiswa.Mushure mekunge iyo masterbatch yeruvara yakasanganiswa nemuchina nepurasitiki resin, inogona kutumirwa kumushini wekuumba jekiseni uine pre-molding mudziyo, uye ruvara rwunofanoumbwa panguva imwe chete.
Kungwarira pakushandisa
Kutanga, huwandu hwekuchena kwefluorescent hunofanirwa kudzorwa zvakanaka.Huwandu hwewhitening agent yakawedzerwa haina kunaka sezvinobvira.Yakawandisa huwandu huchaita kuti plastiki yero.Chechipiri, iyo inopenya uye mbishi zvinhu zvinofanirwa kumutswa zvakaenzana.
Heano nzira shoma dzekushandisa mapurasitiki anopenya, uye iwo chaiwo aunoda kusarudza maererano nemamiriro ako pachako.Kana uine mibvunzo pamusoro pekushandisamapurasitiki anopenya, ndapota inzwa wakasununguka kusiya meseji pabhodhi remeseji.
