Ihe mgbochi usoro phosphine organic mpịachi

ATMP nwere ezigbo chelation, mgbochi dị ala na mgbagha lattice. Ọ nwere ike igbochi ịcha nnu, karịsịa calcium carbonate. ATMP nwere akụrụngwa kemịkalụ kwụsiri ike na mmiri ma ọ naghị adị mfe ịme mmiri. Mgbe ntinye uche dị elu na mmiri, mmetụta mgbochi corrosion ka mma.

HEDP bụ organic phosphonic acid scale na corrosion inhibitor, nke nwere ike ịmepụta ogige kwụsiri ike na ígwè, ọla kọpa, zinc na ion metal ndị ọzọ, ma nwee ike igbari oxides n'elu igwe. Ọ ka nwere ike ịrụ ọrụ dị mma na mgbochi corrosion na ọnụ ọgụgụ na 250 ℃, ọ ka na-akwụsi ike na ọnụ ahịa pH dị elu, ọ dịghịkwa mfe iji hydrolyze na decompose n'okpuru ọnọdụ photothermal n'ozuzu. Nguzogide acid, alkali na chlorine oxidation dị mma karịa organic phosphonic acid (nnu).

Edtmps bụ ụdị polyphosphate organic nwere nitrogen, nke bụ ihe mgbochi corrosion cathode. E jiri ya tụnyere polyphosphate inorganic, edtmps abawanyela ugboro 3-5. Ọ bụ mmiri na-adịghị mma, nke na-adịghị egbu egbu na enweghị mmetọ, na-enwe ezigbo nkwụsi ike kemịkal na nguzogide okpomọkụ. Ọ ka nwere mmetụta mgbochi ọnụ ọgụgụ dị mma na 100 ℃. Edtmps nwere ike decomposed n'ime asatọ nti na-adịghị mma ion na aqueous ngwọta, chelating dị iche iche metal ion na-etolite a macromolecular mgbagwoju netwọk na monomer Ọdịdị, nke rụrụ arụ na gbasasịa na mmiri na-ebibi nkịtị crystallization nke calcium ọnụ ọgụgụ. Ọ nwere mmetụta mgbochi dị mma na calcium sulfate na barium sulfate.

Edtmpa nwere ikike siri ike chelate ion metal, na mgbagwoju anya ya na ion ọla kọpa buru ibu karịa nke ndị ọrụ chelating niile gụnyere EDTA. Edtmpa bụ reagent na-adịghị egbu egbu. Enwere ike iji ya dị ka onye na-ehicha ihe maka chips semiconductor na ụlọ ọrụ eletrọnịkị ma jiri ya mee ihe maka ịmepụta sekit agbakwunyere; na ụlọ ọrụ ọgwụ, dị ka onye na-ebu ihe redioactive, a na-eji ya maka nyocha na ọgwụgwọ ọrịa; ikike chelating nke edtmpa dị elu karịa nke EDTA na DTPA, na ihe fọrọ nke nta ka ọ bụrụ ihe niile nwere ike dochie edtmpa, ebe a na-eji EDTA mee ihe dị ka onye na-emepụta ihe.

Ọ bụ nnu sodium na-anọpụ iche nke ATMP, nke nwere ike igbochi nnu na-egbuke egbuke ka ọ bụrụ ọnụ ọgụgụ, karịsịa calcium carbonate scale. ATMP?

Mpịakọta polycarboxylic acid ihe mgbochi na ihe na-ekesa

PAAS abụghị ihe na-egbu egbu, na-agbaze na mmiri, a pụkwara ịrụ ya na alkaline na ọnọdụ ntinye uche na-enweghị nkwụsị. PAAS nwere ike gbasasịa calcium carbonate, calcium sulfate na ndị ọzọ nnu microcrystals ma ọ bụ sedimenti na mmiri na-enweghị mmiri ozuzo iji nweta nzube nke ọnụ ọgụgụ mgbochi.

AA / AMPS bụ copolymer nke acrylic acid na 2-acrylamide-2-methylpropanesulfonic acid (AMPS). N'ihi na ihe molekụla ahụ nwere otu carboxyl na otu polar sulfonic acid siri ike nwere mgbochi dị mma yana arụ ọrụ mgbasa, enwere ike ịkwalite nguzogide calcium. Mmetụta mgbochi nke calcium phosphate, calcium carbonate na zinc scale na mmiri doro anya, na ịrụ ọrụ mgbasa ozi dị mma. Mgbe agwakọtara ya na phosphine organic, mmetụta synergistic pụtara ìhè. Ọ kachasị mma maka mmiri nwere pH dị elu, alkalinity dị elu na ike siri ike. Ọ bụ otu n'ime ndị na-egbochi ọnụ ọgụgụ kachasị mma na ndị na-ekesa iji nweta nnukwu ntinye uche na ọtụtụ ọrụ.

PESA bụ ụdị “akwụkwọ ndụ akwụkwọ ndụ” ọtụtụ ihe na-egbochi corrosion na-enweghị phosphorus na nitrogen.
