Ndi mankhwala otani omwe amayenera kugwiritsidwa ntchito popanga phosphate? Kodi chimagwira ntchito yanji musanalandire chithandizo?
China phosphate, Hebei phosphate, Phosphate, phosphate China, wopanga phosphate, phosphate katundu,
1. Zambiri zoyambira
Molecular formula: H3PO4
Zomwe zili: Asidi ya phosphoric acid (85%, 75%) ya phosphoric acid (85%, 75%)
Kulemera kwa mamolekyu: 98
CAS NO: 7664-38-2
Kupanga mphamvu: 10,000 matani / chaka
Kupaka: migolo ya pulasitiki ya 35Kg, migolo ya pulasitiki ya 300Kg, migolo ya tani
2. Muyezo wa khalidwe la mankhwala

3. Gwiritsani ntchito
ulimi: Asidi wa Phosphoric ndizofunikira kwambiri popanga feteleza wa phosphate (superphosphate, potassium dihydrogen phosphate, etc.) ) zopangira.
Makampani: Phosphoric acid ndi chinthu chofunikira kwambiri chamankhwala, ndipo ntchito zake zazikulu ndi izi:
1. Tetezani zitsulo pamwamba ndikupanga filimu yosasungunuka ya phosphate pamwamba pazitsulo kuti muteteze zitsulo kuti zisawonongeke.
2. Kusakaniza ndi nitric acid monga mankhwala opukuta mankhwala kuti apititse patsogolo kusalala kwazitsulo.
3. Phosphateesters, zopangira zopangira zotsukira ndi mankhwala ophera tizilombo.
4. Zida zopangira zopangira phosphorus yokhala ndi flame retardants
Chakudya: Phosphoric acid ndi chimodzi mwazowonjezera pazakudya. Amagwiritsidwa ntchito mu chakudya ngati wowawasa wothandizira ndi mchere yisiti. Coca-Cola ili ndi phosphoric acid.Phosphate ndi gawo lofunikira lazakudya ndipo litha kugwiritsidwa ntchito ngati chowonjezera zakudya.
The zitsulo pamwamba "phosphorification mankhwala". Otchedwa phosphorous amatanthauza njira yopanga zitsulo workpieces kudzera njira acidic munali dihydrogen -mankwala mchere, ndi njira kupanga khola insoluble mankwala nembanemba pamwamba pake kupanga mankhwala anachita. Nembanembayo imatchedwa filimu ya phosphorum. Cholinga chachikulu cha filimu ya phosphorum ndikuwonjezera kumamatira kwa filimu yokutira ndikuwongolera kukana kwa dzimbiri kwa zokutira. Pali njira zambiri zopangira phosphoric. Malinga ndi kutentha pa phosphorous, akhoza kugawidwa mu kutentha kwa phosphorous (90-98 ° C), sing'anga kutentha phosphorous (60-75 ° C), otsika kutentha phosphate (35-55 ° C) ndi N chipinda kutentha phosphorous.
Tekinoloje ya passivation ya filimu ya phosphorum imagwiritsidwa ntchito kwambiri ku North America ndi mayiko aku Europe. Kugwiritsa ntchito ukadaulo wa passivation kumatengera mawonekedwe a filimu ya phosphate palokha. Filimu ya phosphorum ndi yopyapyala. Kawirikawiri, ndi 1-4g / m2, yomwe siidutsa 10g / M2, malo ake a pore aulere ndi aakulu, ndipo filimuyo imakhala ndi kukana kwa dzimbiri kochepa. Ena amakhala ndi dzimbiri lachikasu msanga poyanika. Pambuyo pa phosphorous, chithandizo cha passivation ndi chotsekedwa chikhoza kuwonjezeredwa ndi zitsulo zomwe zimawonekera mu pores za filimu ya phosphorurative, kapena kusanjikizako kumapangidwa. Mphamvu ya okosijeni imapangitsa kuti phosphate ikhale yokhazikika mumlengalenga.

Filimu yotembenuza phosphate imagwiritsidwa ntchito muchitsulo, aluminium, zinki, cadmium, ndi ma alloys ake, omwe angagwiritsidwe ntchito ngati gawo lomaliza loyengedwa kapena ngati gawo lapakati la zigawo zina zophimba. Udindo wake uli ndi mbali zotsatirazi.

Ngakhale Kuwongolera phosphorurative filimu ndi woonda, chifukwa si zitsulo sanali conductive kudzipatula wosanjikiza, akhoza kusintha kondakitala pamwamba pa zitsulo workpiece mu chokhwima kondakitala, ziletsa mapangidwe yaying'ono - magetsi padziko lapansi. chogwirira ntchito chachitsulo Kuwonongeka kwa filimu yokutira. Table 1 imatchula zotsatira za filimu ya phosphate pa kukana dzimbiri zachitsulo.
Kupititsa patsogolo filimu yomatira pakati pa matrix ndi zokutira kapena zigawo zina zokongoletsera za organic ndi dongosolo lonse lolimba lomwe limaphatikiza kuphatikiza kwapafupi. Palibe malire owonekera panthawiyi. The porous zimatha phosphorurative filimu kupanga chatsekedwa wothandizira, zokutira, etc. kulowa mu pores izi, ndi kumangiriza kwa phosphoridized nembanemba, kuti patsogolo adhesion.

Perekani woyera padziko phosphorous filimu akhoza kukula pamwamba pa zitsulo workpiece popanda kuipitsa mafuta ndi dzimbiri wopanda wosanjikiza. Chifukwa chake, zida zachitsulo zomwe zakhala phosphorous zimatha kupereka malo oyera, yunifolomu, opanda mafuta komanso dzimbiri.
