Phthalic Anhydride ya Maemo a a Kwa Godimo (PA): Selo sa Botlhokwa se se Agang Dipolymer le Dikhemikhale tse di Dirang sentle thata

Dikarolo tse dikgolo tsa Tiriso

1. Diresine tsa Polyester le Dipolasetiki tsa Mogote: Motheo wa Dipolymer tsa Madirelo
Phthalic Anhydride e dirisiwa thata mo tlhagisong ya diresini tsa polyester tse di sa kgotsofalang (di-UPR), e leng karolo e e botlhokwa mo dipolasetiking tse di nonotshitsweng ka galase ya faeba (di-FRP):
Ditiriso tsa FRP:
Mo tlhagisong ya dikoloi (sekao, batlhagisi ba dikoloi ba Yuropa), di-UPR tse di tswang mo PA di dirisiwa go tlhagisa diphanele tsa mmele tse di botlhofo, di-bumper, le dikarolo tse di ka fa tlase ga hood, go fokotsa bokete jwa koloi le go tokafatsa bokgoni jwa lookwane.
Mo maatleng a phefo, diresini tse di theilweng mo PA di botlhokwa mo go direng di-blade tsa thebine ya phefo, go tlamela ka maatla a a kwa godimo le go tshwarelela go emelana le maemo a bosa a a feteletseng mo dipolaseng tse di kwa ntle ga lewatle (sekao, diporojeke tsa Lewatle la Bokone).
Ditlaleletsi tsa Polasetiki e e Mogote:
E dira jaaka sefetoledi mo tlhagisong ya polyvinyl chloride (PVC), e tokafatsa go fetofetoga le maemo le go kgona go dira. Ka sekai, mo difemeng tsa dipeipi tsa PVC tsa Asia, di-polasetiki tse di theilweng mo PA di tokafatsa go emelana le dipeipi tsa dithulaganyo tsa metsi le tsa kgeleloleswe.

2. Dipente, Dipente, le Dikgomaretsi: Go Dira sentle le go Tshwarelela
Diresine tsa Alkyd:
PA ke motswako wa botlhokwa mo diresing tsa alkyd, tse di dirisiwang mo dipente tsa kago (sekao, dipente tsa ntlo tsa kwa ntle kwa Amerika Bokone) ka ntlha ya go emelana le maemo a bosa a a gaisang le go boloka mmala. Dikhurumelo tse di theilweng mo alkyd gape di sireletsa difatlhego tsa tshipi mo mafelong a madirelo (sekao, maborogo, metšhini) mo go boleng.
Dipeo tsa Epoxy:
Mo dikhurumelong tse di kopantsweng, ditswakwa tsa PA di tokafatsa kgomarelo le go emelana le dikhemikhale tsa dithulaganyo tsa epoxy, tse di botlhokwa thata mo go tsenyeng fa fatshe mo diphaposing tse di phepa tsa melemo le mo mafelong a go dira dijo.
Dikgomaretsi:
E sebediswa ka 热熔胶 (dikgomaretsi tse qhibidihang tse chesang) bakeng sa ho phuthela le ho bofa dibuka, PA e ntlafatsa ntlha ya ho qhibidiha le matla a ho kopanya, ho netefatsa tshebetso e tshepahalang meleng ya tlhahiso e lebelo le phahameng (mohlala, indasteri ya ho phuthela ya Yuropa).

3. Dipolasetiki le Dikhemikale tse di Kgethegileng: Go Tokafatsa Dinonofo tsa Didirisiwa
Dipolasetiki tsa Phthalate:
PA ke setlhogo sa go tlhagisa diisononyl phthalate (DINP) le diethyl phthalate (DEP), e e dirisiwang thata mo ditlhagisweng tsa PVC jaaka ditshamekisi, dikhurumelo, le didirisiwa tsa kalafi. Dipolasetiki tseno di tokafatsa go fetofetoga le maemo fa di ntse di boloka kobamelo ya melawana ya EU REACH ya botlhole jo bo kwa tlase (sekao, mo ditlhagisweng tsa bana).
Didirisiwa tsa Magareng tsa Melemo:
Mo tshwaraganong ya melemo, ditswakwa tsa PA di dirisiwa mo tlhagisong ya melemo e e jaaka diokobatsi tse di lwantshang go ruruga le metswako ya di-antifungal. Ka sekai, e na le seabe mo go tlhakanyeng dibolayamegare tsa cephalosporin, tse di botlhokwa thata mo go alafeng ditshwaetso tsa dibakateria lefatshe ka bophara.

4. Temothuo le Taolo ya Disenyi: Ditharabololo tse di Tswelelang Pele
Dibolayatshenekegi le Dibolayafankase:
Dikhemikhale tse thehilweng hodima PA di sebediswa ho hlophiseng dihlahiswa tsa tshireletso ya dijalo, tse kang di-pyrethroid tsa maiketsetso bakeng sa taolo ya dikokonyana. Mo dipolaseng tsa dinawa tsa soya tsa Amerika Borwa, metswako eno e thusa go sireletsa dijalo mo disenyi tse di tlhaselang fa e ntse e fokotsa tshusumetso ya tikologo.
Dipolymer tse di kgonang go bola mo ditsheding:
Jaaka monomere mo dipolasetiking tse di bolayang ditshedi, PA e na le seabe mo tlhabololong ya didirisiwa tsa go phuthela tse di sa senyegeng tikologo (sekao, ditshodi tsa dijo tse di theilweng mo dimeleng) tse di fokotsang go ikaega ka ditlhagiswa tse di theilweng mo peterolong.

5. Ditiriso tsa Laboratori le tsa Patlisiso
Tshwaraganyo ya Ditshedi:
PA ke sediriswa se se farologaneng mo dilaboratoring tsa thuto le tsa madirelo tsa ditsibogo tse di jaaka acylation ya Friedel-Crafts, e e dirisiwang go tlhama di-ketone le difetolammala tse di nkgang monate. E boetse e nolofatsa tlhahiso ya phthalimide, e leng ntho e bohareng ya bohlokwa diphuputsong tsa meriana le tsa agrochemical.
Saense ya Dipolymer:
E dirisiwa mo dilaboratoring tsa dipolymer go ithuta dikamano tsa popego le dithoto tsa dipolyester, go kgontsha tlhabololo ya didirisiwa tsa maemo a a kwa godimo tsa difofane le tsa ileketeroniki (sekao, dikhurumelo tse di sa kgoneng go emelana le mogote tsa disatelaete).

Letlhare la Taolo ya Boleng

Ka bokhutshwane

Boleng le Go ikobela melao
Dikereiti tsa Bophepa:
Mophato wa Indasteri: ≥99.5% bohloeki, bo loketse tlhahiso ya resin le polasetiki, bo kopana le maemo a ISO 9001.
Mophato wa Melemo: E tsamaisana le EP le USP go dirisiwa mo dilong tse di magareng tsa melemo, ka diteng tsa tshipi e e bokete ≤10 ppm.
Pabalesego le Tsweletsopele:
E dirilwe mo mafelong a a netefaditsweng ke ISO 14001 go dirisiwa oksijene ya o-xylene, ka dithulaganyo tsa go busetsa mogote wa matlakala go fokotsa motlhala wa khabone.
E phuthetswe ka dikgetsana tsa 25 kg kapa di-tote tsa 1000 kg, e ngotswe ka ditlhagiso tsa kotsi tsa GHS bakeng sa ho tshwarwa le ho tsamaiswa ka tsela e bolokehileng (e ikamahanya le IMDG/ADR).

Ke Eng fa re Tlhopha Anhaetereite ya Rona ya Phthalic?
Ebang o hlahisa thepa e latelang e kopantsweng ya moloko o latelang, o etsa dikhurumetso tse sebetsang hantle, kapa o ntshetsa pele dipolasetiki tse tshwarehang, PA ya rona e fana ka tsibogo e tsitsitseng le bohlweki. Ka ditsi tsa phepelo tsa lefatshe ka bophara Amerika Leboya, Yuropa, le Asia, re netefatsa thomelo e tshepahalang le tshehetso ya sethekniki bakeng sa dikopo tse tlohang dithulaganyong tse kgolo tsa indasteri ho ya diporojekeng tsa dipatlisiso tsa niche.
