Sebopeho sa limolek'hule tsa sehlahisoa:
Phosphoric acid ke ntho e se nang 'mala, e sa nkheng, e tiileng ka kristale kapa ke mokelikeli o motenya oa sirapo.Boemo ba 'mele bo itšetlehile ka matla le mocheso.
Asiti ea phosphoric e kopaneng e hlaha joalo ka mokelikeli o se nang 'mala, o sa nkhang hamonate, o nang le syrupy.E na le tatso e monate ea asiti ha e hlapolotsoe ka nepo.
Asiti e hloekileng ea phosphoric, eo hape e bitsoang orthophosphoric acid, ke acid e hlakileng, e se nang mebala, ea liminerale e nang le matla a itekanetseng.Hangata e rekisoa e le tharollo ea metsi ea 75-85% moo e leng teng e le mokelikeli o hlakileng, o hlakileng.
Phosphoric acid ea boemo ba lijo e sebelisetsoa ho etsa asiti ea lijo le lino.E fana ka tatso e monate kapa e bolila mme, kaha ke k'hemik'hale e hlahisoang ka bongata, e fumaneha ka theko e tlaase le ka bongata.Phosphoric acid, e sebelisoang linong tse ngata tse bonolo, e 'nile ea amahanngoa le ho fokotseha ha masapo lithutong tsa lefu la seoa.Ka bokhuts'oanyane, asiti ea phosphoric ke asiti e matla le lik'hemik'hale tse tloaelehileng tsa indasteri tse sebelisoang ho etsa lihlahisoa tse ngata, haholo lihloekisi tsa porcelain le tšepe, litlolo le menontsha.E boetse e sebelisoa e le motsoako oa lijo 'me ke karolo e kholo ea lino-mapholi tse ngata.Metsoako e tlaase ea phosphate e fumanoa metsing a nooang ao e ekeletsoang ho ’ona libakeng tse ling e le ho fokotsa ho qhibiliha ha loto.
Asiti ea phosphoric ke ea bobeli ho ea sulfuric acid e le esiti ea indasteri 'me e lula e le maemong a holimo ho 10 a lik'hemik'hale tse sebelisoang lefatšeng ka bophara, empa e sebelisoa lits'ebetsong tse ling tse ngata.Phosphates e ne e sebelisoa e le lihahi le tse nolofatsang metsi.Sehahi ke ntho e kentsoeng lisepeng kapa sesepa ho eketsa matla a tsona a ho hloekisa.
Phosphoric acid e sebelisoa e le karolo e bohareng ea tlhahiso ea lijo tsa liphoofolo, lik'hemik'hale tsa phekolo ea metsi, phekolo ea tšepe ea holim'a tšepe, etching agent, le lihlahisoa tsa tlhokomelo ea botho tse kang sesepa sa meno.E sebelisoa e le sesosa sa indasteri ea peterole le polymer.Phosphoricacid e sebelisoa lijong e le ntho e sireletsang, e etsang acidulant, le tatso e matlafatsang;e etsa hore lino tse nang le carbonate tse kang Coca Cola le Pepsi li be le asiti, 'me li etsa hore li be le tatso e monate.Asiti ea phosphoric e sebelisoa joalo ka ho tlosa arust le ho hloekisa tšepe.Naval Jelly ke hoo e ka bang 25% ea asiti ea phosphoric.Litšebeliso tse ling tsa asiti ea phosphoric e kenyelletsa taolo ea opacity tlhahiso ea likhalase, ho daea masela, latexcoagulation ea rabara le lisamente tsa meno.
Phosphoric acid (H3PO4) ke oxoacid ea bohlokoa ka ho fetisisa ea phosphorus 'me tšebeliso ea eona e kholo ke ha ho etsoa menontsha.
Ka hare ho 'mele oa motho, phosphate ke motsoako o ka sehloohong o nang le phosphorus.Phosphate ke motsoako oa inorganic mme ke letsoai la phosphoric acid.E ka etsa li-esters tsa manyolo tse nang le metsoako e fapaneng 'me tsena ke tsa bohlokoa lits'ebetsong tse ngata tsa biochemical.Phosphate e na le foromo ea maiketsetso PO43-.Ke molek'hule ea tetrahedral, moo athomo e bohareng ea phosphorus e pota-potiloeng ke liathomo tse 'nè tsa oksijene.
Litsamaisong tsa likokoana-hloko, phosphate e atisa ho fumanoa e le ion ea mahala (inorganic phosphate) kapa e le ester ka mor'a ho itšoara ka metsoako ea tlhaho (hangata e bitsoa organic phosphates).Inorganic phosphate (haholo e hlalosoa e le Pi) ke motsoako oa HPO42- le H2PO4- ho pH ea 'mele.
Chemwin e ka fana ka mefuta e mengata ea li-hydrocarbon tse ngata le li-solvents tsa lik'hemik'hale bakeng sa bareki ba indasteri.Pele ho moo, ka kopo bala lintlha tse latelang mabapi le ho etsa khoebo le rona:
1. Tshireletso
Tšireletseho ke eona ntho e tlang pele bophelong ba rona.Ntle le ho fa bareki tlhahisoleseling mabapi le ts'ebeliso e sireletsehileng le e baballang tikoloho ea lihlahisoa tsa rona, re boetse re ikemiselitse ho netefatsa hore likotsi tsa polokeho ea basebetsi le borakonteraka li fokotsoa ho ba bonyane bo utloahalang le bo ka khonehang.Ka hona, re hloka hore moreki a etse bonnete ba hore litekanyetso tse nepahetseng tsa ho laolla le ho boloka polokeho li fihlelleha pele ho pepa ha rona (ka kopo sheba sehlomathiso sa HSSE ho latela maemo le maemo a kakaretso a thekiso ka tlase).Litsebi tsa rona tsa HSSE li ka fana ka tataiso mabapi le litekanyetso tsena.
2. Mokhoa oa ho fana
Bareki ba ka odara le ho fana ka lihlahisoa ho tsoa ho chemwin, kapa ba ka fumana lihlahisoa ho tsoa femeng ea rona ea tlhahiso.Mekhoa e teng ea lipalangoang e kenyelletsa lipalangoang tsa literaka, terene kapa mefuta e mengata (maemo a arohaneng a sebetsa).
Tabeng ea litlhoko tsa bareki, re ka hlakisa litlhoko tsa likepe kapa litanka mme ra sebelisa litekanyetso tse khethehileng tsa polokeho / tlhahlobo le litlhoko.
3. Palo e fokolang ea taelo
Haeba u reka lihlahisoa sebakeng sa rona sa marang-rang, palo e tlase ea odara ke lithane tse 30.
4.Tefo
Mokhoa o tloaelehileng oa ho lefa ke ho fokotsa ka kotloloho matsatsing a 30 ho tsoa ho invoice.
5. Litokomane tsa thomello
Litokomane tse latelang li fanoe ka thomello ka 'ngoe:
· Bill of Lading, CMR Waybill kapa tokomane e 'ngoe e amehang ea lipalangoang
· Setifikeiti sa Tlhahlobo kapa Tumellano (haeba ho hlokahala)
· Litokomane tse amanang le HSSE tumellanong le melaoana
· Litokomane tsa meetlo ho latela melaoana (haeba ho hlokahala)
