Kutholakale ukuthi i-Alumina ikhona okungenani izinhlobo ezingu-8, ziyi-α-Al2O3, θ-Al2O3, γ-Al2O3, δ-Al2O3, η-Al2O3, χ-Al2O3, κ-Al2O3 kanye ne-ρ-Al2O3, izakhiwo zazo zesakhiwo se-macroscopic nazo zihlukile. I-Gamma activated alumina iyikristalu ehlanganisiwe ecishe ibe yi-cubic, enganyibiliki emanzini, kodwa encibilikayo ku-asidi kanye ne-alkali. I-Gamma activated alumina iyisisekeli esibuthakathaka se-asidi, inephuzu lokuncibilika eliphezulu elingu-2050 ℃, ijeli ye-alumina ngesimo se-hydrate ingenziwa ibe yi-oxide ene-porosity ephezulu kanye nobuso obuthile obuphezulu, inezigaba zokuguquka ebangeni lokushisa elibanzi. Ekushiseni okuphezulu, ngenxa yokuphelelwa amanzi emzimbeni kanye ne-dehydroxylation, ubuso be-Al2O3 bubonakala buhambisana ne-oxygen engagcwalisiwe (isikhungo se-alkali) kanye ne-aluminium (isikhungo se-asidi), nomsebenzi we-catalytic. Ngakho-ke, i-alumina ingasetshenziswa njengomthwali, i-catalyst kanye ne-cocatalyst.I-alumina esebenzayo ye-Gamma ingaba yi-powder, ama-granule, ama-strips noma ezinye. Singenza njengoba ufuna. I-γ-Al2O3, ebizwa ngokuthi "i-alumina esebenzayo", uhlobo lwezinto eziqinile ezisakazeka kalula, ngenxa yesakhiwo sayo se-pore esilungisekayo, indawo enkulu ethile, ukusebenza okuhle kokumuncwa, ubuso obunezinzuzo ze-acidity kanye nokuqina okuhle kokushisa, ubuso obune-microporous obunezakhiwo ezidingekayo zesenzo se-catalytic, ngakho-ke iba yi-catalyst esetshenziswa kakhulu, i-catalyst carrier kanye ne-chromatography carrier embonini yamakhemikhali namafutha, futhi idlala indima ebalulekile ekuqhekekeni kwamafutha, ekuhlanzeni i-hydrogenation, ekuguqulweni kwe-hydrogenation, ekuphenduleni kwe-dehydrogenation kanye nenqubo yokuhlanza ukukhishwa kwemoto. I-Gamma-Al2O3 isetshenziswa kabanzi njenge-catalyst carrier ngenxa yokulungiswa kwesakhiwo sayo se-pore kanye ne-acidity ebusweni. Uma i-γ-Al2O3 isetshenziswa njenge-catalyst carrier, ngaphezu kwalokho ingaba nemiphumela yokusabalalisa nokuzinzisa izingxenye ezisebenzayo, inganikeza futhi isikhungo esisebenzayo se-acid alkali, ukusabela okuhambisanayo nezingxenye ezisebenzayo ze-catalytic. Isakhiwo sembobo kanye nezakhiwo zobuso be-catalyst zincike ku-catalyst ye-γ-Al2O3, ngakho-ke i-catalyst esebenza kahle kakhulu ingatholakala ukuze kutholakale ukusabela okuthile kwe-catalytic ngokulawula izakhiwo ze-catalyst ye-gamma alumina.I-alumina esebenzayo ye-gamma ngokuvamile yenziwa nge-pseudo-boehmite yayo yangaphambili ngokusebenzisa ukuphelelwa amanzi emzimbeni okuphezulu okungu-400 ~ 600℃, ngakho-ke izakhiwo ze-physicochemical ebusweni zinqunywa kakhulu yi-pseudo-boehmite yayo yangaphambili, kodwa kunezindlela eziningi zokwenza i-pseudo-boehmite, futhi imithombo ehlukene ye-pseudo-boehmite iholela ekuhlukeni kwe-gamma - Al2O3. Kodwa-ke, kulawo ma-catalyst anezidingo ezikhethekile kumthwali we-alumina, kunzima ukufeza kuphela ukulawula i-pseudo-boehmite yangaphambili, okumele kuthathwe ekulungiseleleni i-prophase kanye nokucubungula ngemuva kokuhlanganisa izindlela zokulungisa izakhiwo ze-alumina ukuze kuhlangatshezwane nezidingo ezahlukene. Lapho izinga lokushisa liphakeme kune-1000 ℃ ekusetshenzisweni, i-alumina iyenzeka ngemuva kokuguqulwa kwesigaba: γ→δ→θ→α-Al2O3, phakathi kwazo γ、δ、θ ziyi-cubic close packing, umehluko ukhona kuphela ekusatshalalisweni kwama-ion e-aluminium ku-tetrahedral kanye ne-octahedral, ngakho-ke lokhu kuguqulwa kwesigaba akubangeli ukushintshashintsha okukhulu kwezakhiwo. Ama-ion e-oxygen esigabeni se-alpha asondelene kakhulu, izinhlayiya ze-aluminium oxide zihlangana kabusha kakhulu, indawo ethile yobuso yehle kakhulu.

I-Meperfluthrin
Igama Lento Inombolo ye-CAS Amaphesenti Adingekayo Isaziso I-Meperfluthrin 352271-52-499% Izinga Lokuhlaziya Kwethulwa i-Meperfluthrin, isibulala-zinambuzane esisebenza kahle kakhulu nesinamandla esihlinzeka ngesivikelo esihlala isikhathi eside ezinhlotsheni eziningi zezinambuzane. I-Meperfluthrin iyi-pyrethroid yokwenziwa, eyaziwa ngezakhiwo zayo zokubulala izinambuzane ezingcono kakhulu kanye nobuthi obuphansi bezilwane ezincelisayo. Isithako esisebenzayo esisetshenziswa kakhulu emikhiqizweni eyahlukahlukene yezinambuzane zasekhaya, kufaka phakathi ama-coil omiyane, omata, kanye noketshezi.
I-Meperfluthrin isebenza ngokuphazamisa uhlelo lwezinzwa lwezinambuzane, okuholela ekukhubazekeni nasekufeni ekugcineni. Lokhu kuyenza isebenze kahle kakhulu ekulawuleni nasekuqedeni izinambuzane ezifana nomiyane, izimpukane, amaphela, nezinye izinambuzane ezindizayo nezikhasayo. I-Meperfluthrin inomphumela wokudiliza ngokushesha, okusho ukuthi ivala ngokushesha futhi ibulale izinambuzane lapho zithintana, inikeze impumuzo ngokushesha ekuhlaselweni yizinambuzane.
Enye yezinzuzo ezibalulekile ze-Meperfluthrin umsebenzi wayo ohlala isikhathi eside. Uma isetshenziswa, ihlala isebenza isikhathi eside, inikeza ukuvikelwa okuqhubekayo ezilokazaneni. Lokhu kuyenza ibe yisisombululo esifanele kokubili ukusetshenziswa ngaphakathi nangaphandle, njengoba ingasiza ekudaleni indawo engenazinambuzane emakhaya, ezingadini nasezindaweni zezentengiselwano.
I-Meperfluthrin itholakala ngezindlela ezahlukene, okuhlanganisa ama-coil, omata, kanye nama-liquid vaporizer. Le mikhiqizo ilula futhi kulula ukuyisebenzisa, okwenza ifanele ukusetshenziswa komuntu siqu kanye nochwepheshe. Ama-mosquito coils nama-mosquito mat asekelwe e-Meperfluthrin athandwa kakhulu ezindaweni lapho izifo ezithwalwa omata zivame khona, njengoba enikeza indlela elula nephumelelayo yokuxosha omata nokunciphisa ingozi yokutheleleka.
Ngaphezu kwezakhiwo zayo zokubulala izinambuzane, i-Meperfluthrin yaziwa nangokungakhiphi iphunga layo kanye nokuguquguquka okuncane, okwenza kube ukukhetha okuphephile nokujabulisayo kokusetshenziswa endlini. Ngokungafani nezinye izibulala-zinambuzane, i-Meperfluthrin ayikhiqizi iphunga noma umusi onamandla, okwenza kube lula kakhulu kubasebenzisi kanye nemindeni yabo. Lokhu kwenza kube ukukhetha okuhle kakhulu emindenini enezingane nezilwane ezifuywayo, njengoba kunciphisa ingozi yokuchayeka kumakhemikhali ayingozi.
I-Meperfluthrin nayo inobungani nemvelo, njengoba yonakala ngokushesha endaweni ezungezile futhi ingashiyi izinsalela eziyingozi. Lokhu kuyenza ibe ukukhetha okunesibopho kokulawula izinambuzane, njengoba kunciphisa umthelela ohlelweni lwemvelo futhi kusekela imikhuba yokuphathwa kwezinambuzane okusimeme.
Uma usebenzisa imikhiqizo esekelwe ku-Meperfluthrin, kubalulekile ukulandela imiyalelo enikezwe umenzi futhi uthathe izinyathelo zokuphepha ezidingekayo ukuqinisekisa ukusetshenziswa okuphephile nokuphumelelayo. Kunconywa ukugwema ukuthintana ngqo kwesikhumba nemikhiqizo futhi uyisebenzise ezindaweni ezinomoya omuhle. Ngaphezu kwalokho, kubalulekile ukugcina imikhiqizo endaweni ephephile, kude nezingane nezilwane.
Sekukonke, i-Meperfluthrin iyisisombululo esisebenza kahle kakhulu, esiphephile, nesilula sokulawula nokuqeda izinhlobo eziningi zezinambuzane. Kungakhathaliseki ukuthi isetshenziswa ngumuntu siqu noma ngochwepheshe, imikhiqizo esekwe ku-Meperfluthrin inikeza isivikelo esithembekile nesihlala isikhathi eside ezinambuzaneni, esiza ekudaleni indawo yokuhlala nokusebenza enempilo nekhululekile.
