1. Hemical Nature na Architectural Characteristics
1.1 Mkpịsị ahụ nke Molecular na Omume Mgbakọ Onwe Onye
(Calcium Stearate ntụ ntụ)
Calcium stearate ntụ ntụ bụ ncha ọla nke stearic acid mebere– Acid fatty juputara na C18– na calcium hydroxide ma ọ bụ calcium oxide, na-emepụta usoro kemịkalụ Ca(C ₁₈ H ₃₅ O ABỤỌ)ABỤỌ.
Ngwakọta a sitere na klas sara mbara nke ncha nchara alkali, nke na-egosipụta ụlọ amphiphilic n'ihi ụdị molekụla ha abụọ: otu pola, ionic “isi” (calcium ion) na abụọ ogologo, hydrocarbon na-abụghị polar “ọdụ” ewepụtara site na agbụ stearic acid.
Na steeti siri ike, ụmụ irighiri ihe ndị a na-agbakọta n'onwe ha ozugbo n'ime usoro lamellars dị larịị site na nkwukọrịta van der Waals n'etiti ọdụ hydrophobic., ebe akụrụngwa calcium ionic na-enye nkwurịta okwu ụkpụrụ ụlọ site na iji nrụgide electrostatic.
Atụmatụ a dị iche iche na-akwado ọrụ ya dị ka ma onye na-egbochi mmiri na lube, na-ekwe ka arụmọrụ gafee usoro ngwaahịa dị iche iche.
Ụdị kristal nke calcium stearate na-abụkarị monoclinic ma ọ bụ triclinic, na-adabere na njikwa ọnọdụ, ma gosipụta nkwụsi ike thermal ruo ihe dị ka 150– 200 Celsius C tupu ire ere amalite.
Solubility ya dị ala na mmiri na ọtụtụ ihe mgbaze anụ ahụ na-eme ka ọ dabara adaba maka ngwa na-akpọ maka mgbanwe n'elu ala na-agbanwe agbanwe na-enweghị leaching..
1.2 Ụzọ synthesis na ụzọ nrụpụta ụlọ ọrụ
Ngwa ngwa, A na-emepụta calcium stearate site na nkuzi isi abụọ: saponification kwụ ọtọ na nzaghachi metathesis.
Na usoro saponification, A na-aza stearic acid na calcium hydroxide n'ime ngwá ọrụ aqueous n'okpuru ọkwa okpomọkụ a na-achịkwa (na-emekarị 80– 100 Celsius C), rapara na nzacha, nhicha, ma fesa ihicha ka ọ dị mma, ntụ ntụ n'efu.
N'aka nke ọzọ, metathesis gụnyere ịza sodium stearate na nnu calcium soluble dị ka calcium chloride, na-eme ka calcium stearate dị ngwa mgbe ọ na-emepụta sodium chloride dị ka ngwaahịa sitere na ya, nke a na-ewepụ ya na nchacha dị ukwuu.
Nhọrọ nke ụzọ na-emetụta mgbasa nke ntanye, ịdị ọcha, na ihe fọdụrụ mmiri mmiri– nkọwapụta igodo na-emetụta arụmọrụ na ngwa eji eme ihe.
Àgwà dị elu nke ịdị ọcha, karịsịa ndị ezubere maka ọgwụ ọgwụ ma ọ bụ ngwaahịa kọntaktị nri, mee usoro nchacha ọzọ iji mezuo ụkpụrụ iwu dịka FCC (Codex kemịkalụ nri) ma ọ bụ USP (United States Pharmacopeia).

Ụlọ mmepụta ihe ọgbara ọhụrụ na-eji reactors na-aga n'ihu na usoro ikpo ọkụ na-akpaghị aka iji na-ekwe nkwa nkwụsi ike na nhazi nke batch-na-batch..
2. Ọrụ na ngwaọrụ bara uru na ngwa ngwaahịa
2.1 mmanu ime na mputa na njikwa polymer
Otu n'ime ọrụ kachasị mkpa nke calcium stearate bụ ihe na-eme ka ọ dị mma na polycarbonate na mmepụta thermoset polymer..
Dị ka mmanu ime, ọ na-ebelata viscosity gbazee site na igbochi esemokwu intermolecular n'etiti ụdọ polymer, na-enyere aka na mgbasa ozi na-adịchaghị mgbagwoju anya n'oge extrusion, ogbugba ịkpụzi, na kalenda usoro.
N'otu oge, dị ka ihe mpụga lube, ọ na-akwaga n'elu ebe polymer a wụrụ awụ ma na-etolite slim, ihe nkiri na-akwalite ntọhapụ na interface n'etiti ihe na nhazi ngwaọrụ.
Omume ejima a na-ebelata nrụpụta ngafe, na-ezere ịnọ na ebu, na enhances elu mkpuchi, N'ihi ya na-emeziwanye arụmọrụ nrụpụta na ihe dị elu.
Ọrụ ya dị mkpa karịsịa na polyvinyl chloride (PVC), ebe ọ na-enyekwa aka na nkwụsi ike nke okpomọkụ site na ikpochapu hydrogen chloride nke ewepụtara n'oge mmebi.
N'adịghị ka ụfọdụ sịntetik lubes, calcium stearate kwụsiri ike n'ime windo ụlọ a na-ejikarị eme ihe ma ọ naghị adalata ngwa ngwa, na-ekwe nkwa ịrụ ọrụ na-agbanwe agbanwe n'oge okirikiri.
2.2 Mgbochi mmiri na ihe mgbochi-caking
N'ihi ọdịdị hydrophobic ya, A na-eji calcium stearate n'ọtụtụ ebe dị ka onye na-ekpuchi mmiri na ihe owuwu ụlọ dị ka ihe, plasta, na plasta.
Mgbe etinyere na matrices ndị a, ọ na-adabara n'elu pore, na-ebelata mmịkọ capillary na ịkwalite nguzogide mmiri na-abanye n'ebughị ụzọ gbanwee n'ụzọ siri ike n'ibu.
Na ngwaahịa powdered– gụnyere nri osisi, nri powders, ọgwụ, na pigmenti– ọ na-eje ozi dị ka onye na-egbochi ịta nri site na ikpuchi iberibe ihe ndị dị n'otu n'otu na ichebe ikpo okwu nke oke iru mmiri na-ebute..
Nke a na-eme ka ịgba ọsọ, na-elekọta, na ngwa ziri ezi, karịsịa na nkwakọ ngwaahịa kọmputa na usoro ngwakọta.
Usoro a na-adabere na nguzobe ihe mgbochi anụ ahụ nke na-egbochi nnabata hygroscopic ma na-ebelata ike mgbakwunye interparticle..
N'ihi na ọ bụ chemically inert n'okpuru ahụkarị nchekwa ọnọdụ, ọ naghị eji ihe ndị na-arụ ọrụ eme ihe, na-ejigide ndụ shelf na arụ ọrụ.
3. Ngwa ngalaba aha gafee ụlọ ọrụ
3.1 Ọrụ na Plastics, Rubber, na Elastomer Production
mmanu mmanu gara aga, Calcium stearate na-arụ ọrụ dị ka onye na-ahapụ ebu na mildew yana scavenger acid na vulcanization roba na mmepụta elastomer sịntetik..
Na-abawanye ụba, ọ na-ekwe nkwa ntọhapụ nke ọma (na-akụtu) na ọta ígwè dị oké ọnụ ahịa na-anwụ site na corrosion nke ngwaahịa acidic butere.
Na polyolefins dị ka polyethylene na polypropylene, Ọ na-akwalite mgbasa nke ihe ndị dị ka calcium carbonate na talc, na-atụnye ụtụ n'ọdịdị mejupụtara morphology.
Ndakọrịta ya na ụdị ihe dị iche iche na-eme ka ọ bụrụ akụkụ a ma ama na nhazi masterbatch.
Ọzọkwa, n'ime plastik ndị na-emebi emebi n'okike, ebe ihe na-ete mmanụ ọdịnala nwere ike igbochi ụzọ mmebi, calcium stearate na-enye nhọrọ dakọtara na eco karịa.
3.2 Jiri na Pharmaceuticals, Ihe ịchọ mma, na Ngwaahịa nri
Na ngalaba ọgwụ, A na-ejikarị calcium stearate mee ihe dị ka glidant na lube na mkpakọ mbadamba, na-eme ka ụfọdụ mgbasa ozi ntụ ntụ mgbe niile na ejection site na iku.
Ọ na-ezere ịrapara na ikpuchi ntụpọ, n'ụzọ kwụ ọtọ na-emetụta nrụpụta nrụpụta yana nkwekọ dose.
Ọ bụ ezie na mgbe mgbagwoju anya na magnesium stearate, A na-ahọrọ calcium stearate n'ụdị ụfọdụ n'ihi nkwụsi ike ya ka ukwuu yana mbelata ohere maka nnyonye anya bioavailability..
N'ihe ịchọ mma, ọ na-arụ ọrụ dị ka onye na-ebu ibu, ihe ngbanwe ọdịdị, na ngwọta stabilizer na powders, ihe owuwu, na lipsticks, na-enye ihe dị nro, ezigbo mmetụta.

4. Nchekwa, Mmetụta gburugburu, na Nlebanya Ọdịnihu
4.1 Profaịlụ Toxicological na ọnọdụ nchịkwa
A na-amatakarị calcium stearate dị ka enweghị ihe egwu (GRAS) site na U.S. FDA mgbe ejiri ya dabere na nnukwu mmepụta omume.
A na-agbanye ya nke ọma na sistem afọ ma na-emezi ya ka ọ bụrụ nke na-eme ka ọ bụrụ abụba abụba na ion calcium., ha abụọ sitere n'echiche anụ ahụ enwere ike ijikwa.
Enweghị ezigbo ihe akaebe nke carcinogenicity, mutagenicity, ma ọ bụ nsị ịmụ nwa ka akọpụtala n'ihe ọmụmụ toxicological nkịtị.
Agbanyeghị, iku ume nke nnukwu ntụ ntụ n'oge njikwa azụmahịa nwere ike ịmepụta ume iku ume, na-eme ka ikuku ikuku dị mma na akụrụngwa nchekwa nkeonwe.
Mmetụta gburugburu ebe obibi dị ntakịrị n'ihi biodegradability ya n'okpuru ọnọdụ ikuku na mbelata nsị mmiri.
4.2 Ụkpụrụ na-ebilite na ihe ndị ọzọ na-adịgide adịgide
Na nkwalite na-elekwasị anya na green kemịkalụ, Ọmụmụ ihe na-elekwasị anya n'ụzọ mmepụta ihe dabere na bio yana mbelata akara ukwu gburugburu ebe obibi na njikọ.
A na-aga n'ihu iji nweta stearic acid site na akụrụngwa na-adigide dịka kernel nkwụ ma ọ bụ tallow., imeziwanye nkwado okirikiri ndụ.
Na mgbakwunye, A na-achọpụta ụdị nanostructured nke calcium stearate maka ịkwalite arụmọrụ mgbasa na belatara ya, nwere ike wedata ojiji ihe n'ozuzu.
Iji ion ndị ọzọ arụ ọrụ ma ọ bụ imekọ ihe na waxes eke nwere ike ịgbasa ike ya na ọkwa pụrụ iche yana sistemụ mwepụta a na-achịkwa..
Na ngwụcha, calcium stearate ntụ ntụ na-egosipụta otu isi ihe organometallic nwere ike isi rụọ nnukwu ọrụ n'ofe azụmahịa., n'ji, na ngalaba nlekọta ahụike.
Ngwakọta ya nke mmanu mmanu, hydrophobicity, kemịkalụ kwụsie ike, na aha iwu na-eme ka ọ bụrụ ihe mgbakwunye isi okwu na sayensị ngwọta ọgbara ọhụrụ.
Dị ka ahịa na-anọgide na-achọ multifunctional, mma, na ihe oriri na-adịgide adịgide, calcium stearate ka bụ ngwaahịa benchmark nwere mkpa na-adịgide adịgide yana ngwa na-emepe emepe.
