①The "Good Manufacturing Practice for Pharmaceutical Products" imati: Kusiyana kwamphamvu pakati pa madera aukhondo ndi malo osadetsedwa komanso pakati pa madera osiyanasiyana aukhondo sikuyenera kuchepera 10Pa.Pakafunika, ma gradient oyenerera ayeneranso kusungidwa pakati pa malo osiyanasiyana ogwirira ntchito (zipinda zogwirira ntchito) zaukhondo womwewo.
②Mchitidwe wa "Veterinary Drug Manufacturing Good Manufacturing Practice" umati: Kusiyana kwapakati pakati pa zipinda zoyera (malo) zokhala ndi ukhondo wosiyanasiyana wa mpweya ziyenera kukhala zazikulu kuposa 5 Pa.
Kusiyana kwamphamvu pakati pa chipinda choyera (malo) ndi chipinda chosayera (malo) chiyenera kukhala chachikulu kuposa 10 Pa.
Kusiyana kwamphamvu kwapakati pakati pa chipinda choyera (malo) ndi mlengalenga wakunja (kuphatikiza madera olumikizidwa mwachindunji ndi kunja) kuyenera kukhala kokulirapo kuposa 12 Pa, ndipo payenera kukhala chipangizo chowonetsa kusiyana kwapakatikati kapena kuwunika ndi alamu.
Pazokambirana zaukhondo pazipinda zazachilengedwe, mtengo wokwanira wa kusiyana kwamphamvu kwapawiri komwe watchulidwa pamwambapa uyenera kutsimikiziridwa molingana ndi zofunikira.
③The "Pharmaceutical Clean Room Design Standards" imati: Kusiyana kwa mpweya wokhazikika pakati pa zipinda zoyera zachipatala zokhala ndi milingo yosiyanasiyana yaukhondo wa mpweya komanso pakati pa zipinda zoyera ndi zipinda zopanda ukhondo sayenera kuchepera 10Pa, komanso kusiyana kwapakati pakati pa zipinda zoyera ndi zamankhwala. mpweya wakunja suyenera kukhala wochepera 10Pa.
Kuphatikiza apo, zipinda zaukhondo zotsatirazi ziyenera kukhala ndi zida zomwe zikuwonetsa kusiyana kwapakatikati:
Pakati pa chipinda choyera ndi chipinda chosayera;
Pakati pa zipinda zoyera zokhala ndi milingo yosiyanasiyana yaukhondo
Mkati mwa malo opangira ukhondo womwewo, pali zipinda zogwirira ntchito zofunika kwambiri zomwe zimafunika kusungitsa kupanikizika koyipa kapena kukakamizidwa kwabwino;
Kutsekera kwa mpweya m'chipinda choyera cha zinthu komanso kukakamiza kwabwino kapena kutsekeka koyipa kwa mpweya kutsekereza kutuluka kwa mpweya pakati pa zipinda zosinthira zaukhondo m'chipinda choyera cha ogwira ntchito;
Njira zamakina zimagwiritsidwa ntchito kunyamula zinthu mosalekeza kulowa ndi kutuluka m'chipinda choyera.
Zipinda zaukhondo zotsatirazi ziyenera kukhala ndi zipinda zokhala ndi zipinda zoyera zachipatala:
Zipinda zoyera za mankhwala zomwe zimatulutsa fumbi panthawi yopanga;
Zipinda zoyera zamankhwala zomwe zosungunulira organic zimagwiritsidwa ntchito popanga;
Zipinda zoyera zachipatala zomwe zimapanga kuchuluka kwa zinthu zovulaza, mpweya wotentha ndi wonyowa komanso wonunkhira panthawi yopanga;
Kuyenga, kuyanika ndi kulongedza zipinda za penicillin ndi mankhwala ena apadera ndi zipinda zawo zopakira pokonzekera.

① The "Electronic Industry Clean Room Design Code" ikuwonetsa kuti kusiyana kwina kokhazikika kuyenera kusungidwa pakati pa chipinda choyera (malo) ndi malo ozungulira.Kusiyana kwa static pressure kuyenera kukwaniritsa malamulo awa:
● Kusiyana kwa mphamvu ya static pakati pa chipinda chilichonse choyera (malo) ndi malo ozungulira kuyenera kutsimikiziridwa malinga ndi zofunikira za kupanga;
● Kusiyana kwamphamvu kwapakati pakati pa zipinda zoyera (magawo) a magawo osiyanasiyana kuyenera kukhala kwakukulu kuposa kapena kufanana ndi 5Pa;
● Kusiyana kwapakati pakati pa chipinda choyera (malo) ndi chipinda chosayera (malo) chiyenera kukhala chachikulu kuposa 5Pa;
● Kuthamanga kwapakati pakati pa chipinda choyera (malo) ndi kunja kuyenera kukhala kwakukulu kuposa 10Pa.
② "Khodi Yopangira Zipinda Zoyera" imati:
Kusiyana kwina kwamphamvu kuyenera kusungidwa pakati pa chipinda choyera (malo) ndi malo ozungulira, ndipo kusiyana kwabwino kapena koyipa kuyenera kusungidwa molingana ndi zofunikira.
Kusiyana kwapakati pakati pa zipinda zoyera zamagulu osiyanasiyana sikuyenera kukhala pansi pa 5Pa, kusiyana kwapakati pakati pa malo oyera ndi malo osayera sikuyenera kukhala osachepera 5Pa, ndipo kusiyana kwapakati pakati pa malo oyera ndi kunja sikuyenera kukhala osachepera 10Pa.
Mpweya wosiyanasiyana womwe umafunika kuti ukhale ndi kusiyana kosiyana kosiyanasiyana m'chipinda choyera uyenera kutsimikiziridwa ndi njira yosokera kapena njira yosinthira mpweya malinga ndi mawonekedwe a chipinda choyera.
Kutsegula ndi kutseka kwa mpweya woperekera ndi kutulutsa mpweya kuyenera kutsekedwa.Mu ndondomeko yolondola yolowera m'chipinda choyera, chowotcha mpweya chiyenera kuyambika kaye, ndiyeno chowotcha mpweya wobwerera ndi kutulutsa mpweya chiyenera kuyambika;potseka, ndondomeko yolumikizirana iyenera kusinthidwa.Njira yolumikizirana ya zipinda zoyera zokhala ndi mphamvu yoyipa ziyenera kukhala zotsutsana ndi zomwe tazitchula pamwambapa kuti zipinda zizikhala zoyera.
Kwa zipinda zoyera zomwe sizikugwira ntchito mosalekeza, mpweya wogwira ntchito ukhoza kukhazikitsidwa molingana ndi zofunikira zopangira, ndipo kuyeretsa mpweya woyeretsa kuyenera kuchitika.
