Yintoni ukumelana nobushushu obufanelekileyo?Misela "umda wokhuseleko" ngokusekelwe kwiimfuno zenkqubo.
Uluhlu olufanelekileyo lokumelana nobushushu bophezulu-ubushushu, obuphezulu{1}}izihluzo zomfezeko azimiselwanga ngokuthanda; kumiselwa lolona qondo lobushushu bokusebenza kunye nokuguquguquka kweqondo lobushushu kwi-oven yetonela. Umgaqo ophambili "kukugubungela inkqubo egqithisileyo ngelixa ushiya umda wokhuseleko."
1. I-Basic Temperature Resistance Bottom Line: i-180 degree
Ubuncinci beqondo lobushushu bokwenza inzala kwii-oveni zetonela yoxubo ngokuqhelekileyo luyi-180℃(umzekelo, ekucoleni okomileyo kwezinye iibhotile zedosi yomlomo). Ke ngoko, ukumelana nobushushu bokucoca kufuneka kuhlangabezene nobuncinci be-180℃ngaphandle kokusilela. Kweli qondo lobushushu, isihluzi seendaba, incamathelisa, kunye nesakhelo kufuneka sigcine uzinzo ngaphandle kokuguqulwa kwe-thermal, ukuqhekeka, okanye ukuphuma.
2. Ukuhambelana kweNkqubo eqhelekileyo: i-250-300 degree
Uninzi lwee-oveni zetonela kwiindawo zokuvelisa ichiza ezitofwayo zisebenzisa inkqubo yokuvala inzala ye-"250℃x 30 minutes" (ethobelana neemfuno ze-GMP zokuphatha isikhongozeli se-aseptic). Ezinye iimveliso zomngcipheko ophezulu-(ezifana nebhayoloji) zide zisebenzise inkqubo yokuvala inzala ka-300. Ngoko ke, kwiimeko ezinjalo, isihluzo esiphakamileyo{6} esinokumelana nobushushu obuyi-300℃okanye ngaphezulu siyafuneka ukuze kuqinisekiswe ukuba ukuhluza akwehli ngexesha{8}}lomjikelo wexesha elide{9}}lobushushu obuphezulu (iiyure ezi-8-12 zokusebenza ngosuku).
3. Umda wokuSebenza ngokugqithisileyo: i-350 degree
Ezinye iinkqubo ezikhethekileyo (ezifana nokususa i-pyrogen enzulu kwiibhotile ezine-lyophilized) zifuna amaqondo obushushu angaphezu kwama-350 degrees. Kwezi meko, isihluzi kufuneka sihlangabezane neemfuno ezingqongqo zokumelana nobushushu bexeshana le-350℃kunye nokumelana nobushushu obuzinzileyo be-320 degree. Ngaphaya koko, uzinzo kufuneka luqinisekiswe ngeemjikelo zomjikelo wobushushu obuninzi obuninzi-(Mkhulu okanye ulingana ne-100 lemijikelo).
Ngaphaya koBubushushu: Izihluzi 'Phezulu{0}}Ukuxhathisa koBubushushu
Okwangoku, ukuhlangabezana neemfuno zobushushu akwanelanga. Iifilitha zee-oveni zokomisa itonela yamayeza kufuneka zibe neempawu ezintathu "zokumelana nobushushu, ukucoceka, kunye nokuzinza":
1. IMathiriyeli yesihluzi: IFayibha yeglasi yeyona "Workhorse"
I-Glass Fiber Filter Material: Ngokumelana nokushisa kwe-350-400 degree, ibonisa ukuzinza okuqinileyo kweekhemikhali kwaye ayikhuphi i-volatiles kumaqondo okushisa aphezulu, okwenza kube yinto ekhethwayo kwiimeko zokusebenza ngaphezu kwe-300 degree.
I-Composite High{0}}Iqondo lobushushu-Isixhobo soHluzo esiNganyangekiyo: Umzekelo, imidibaniso yefiber yeglasi kunye nefibre yeceramic inokumelana namaqondo obushushu angaphezu kwama-400 degree, kodwa kufuneka iqinisekise ukuba akukho mngcipheko wokuchithwa kwefayibha (ukuthintela ukungcoliseka kwesikhongozeli).
Izinto ezingavumelekanga: I-polypropylene eqhelekileyo kunye nezixhobo zokucoca i-polyester zinokumelana nokushisa kwe-80-120℃kuphela kwaye ziya kunyibilika kwaye zibole kumaqondo aphezulu. Azivumelekanga ngokupheleleyo ukuba zisetyenziswe kwii-oveni zokomisa itonela.
2. Amacandelo oLwakhiwo: Susa "iiNgozi eziPhezulu zobushushu{1}}
Isakhelo: Sebenzisa i-304/316 insimbi engenasici ukukhusela i-rust kunye nokukhululwa kwe-ion yensimbi kumaqondo aphezulu.
I-Sealant: Sebenzisa -ubushushu obuphezulu-irubha ye-silicone ekwaziyo ukumelana nobushushu (ubushushu obunganyangekiyo Inkulu kune okanye ilingana ne-300 degree) endaweni yerabha ye-nitrile eqhelekileyo (ukumelana nobushushu Ngaphantsi okanye ilingana ne-120℃) ukunqanda ukuqhekeka kunye nokuvuza kumaqondo obushushu aphezulu.
I-Mesh yeNkxaso: Isixhobo sentsimbi kufuneka singene kunyango lwe-passivation ukunqanda i-oxidation ephezulu{0}}yobushushu kunye nokuveliswa kwamasuntswana.
3. Ukuthobela: Ukupasa "Iikhrayitheriya eZimbini" zokuqinisekisa uKhuseleko
Ukuphumelela koHlelo: Kufuneka uphumelele uvavanyo oluqhelekileyo lwe-EN 1822, kunye nokusebenza kakuhle kwe-H13 okanye ngaphezulu (Enkulu okanye ilingana ne-99.97% @ 0.3μm) ukuqinisekisa ukubanjwa kwazo zonke ii-microorganisms kunye neengqungquthela.
Imfezeko: Emva kokuvala{0}}ubushushu obuphezulu, uphumelele uvavanyo lwengqibelelo ye-PAO/DEHS ngomyinge wokuvuza oNgaphantsi okanye olingana ne-0.01%. Iziphumo zovavanyo kufuneka zihlangabezane neemfuno zokulandelelwa kwedatha ye-GMP.
"Imingcipheko efihliweyo" yokukhetha ubushushu obungalunganga
Ukuba ukuxhathisa kobushushu besihluzi akufanelekanga, iziphumo zingasongela ngokuthe ngqo umgangatho wechiza:
Ukumelana nokushisa okunganeleyo: Isixhobo sokucoca siyancipha kwaye i-carbonizes kwiqondo lokushisa eliphezulu, okubangela ukuhla okubukhali ekusebenzeni kakuhle kokucoca. I-microorganisms yangaphandle okanye i-particulates ingangena kwi-oven kwaye ingcolise izitya.
Ukumelana nobushushu obugqithileyo: Ukukhetha ngobumfama isihluzi sobushushu obungaphezulu-{1}}(umzekelo, ukusebenzisa isihluzi seqondo lama-400 xa eyona nkqubo yobushushu iyi-250 degree) kuya konyusa iindleko zesixhobo (imodeli{6}}ephezulu{7}}iqondo lobushushu zixabisa ka-2-3 ngokuphindwe ka-3 kunemifuziselo eqhelekileyo) kwaye kunokubangela ukuxhathisa okugqithisileyo komoya. ukusebenza komjikelo.
Umgaqo ongundoqo wokumisela "ubushushu obufanelekileyo" bophezulu-ubushushu, obuphezulu{1}}izihluzo ezisebenzayo kwii-oveni zetonela yamayeza kukusebenzisa eyona nkqubo iphezulu yobushushu njengomlinganiselo, ukongeza i-10% -20% yomda wokhuseleko. Umzekelo:
Inkqubo yokuvala inzala ngama-250 → khetha isihluzo esinokumelana nobushushu obungama-300;
Inkqubo yokuvala inzala ngama-300 → khetha isihluzo esinokumelana nobushushu obungama-350.
Kwangaxeshanye, uvavanyo olubanzi kufuneka lwenziwe ngokusekelwe kuzinzo lwemathiriyeli yokucoca, ukuthotyelwa kwesakhiwo, kunye nokuqikelelwa kweendleko. Kungale ndlela kuphela apho izikhongozeli zokupakisha zamayeza zinokuthi zigcine umgca wazo wokugqibela wokukhusela ucoceko kwindawo erhabaxa{1}}yokucocwa kobushushu obuphezulu, ihlangabezana ngokwenyani neemfuno ezingqongqo ze-GMP zommandla wokuvelisa amayeza angcolileyo.
