Opereka zinthu masiku ano akufunsidwa kuti apange zida zomwe zimakwaniritsa zofunikira zachipatala chomwe chikukula.M'makampani omwe akuchulukirachulukira, mapulasitiki ogwiritsidwa ntchito pazida zamankhwala ayenera kukana kutentha, zotsukira, ndi mankhwala ophera tizilombo, komanso kung'ambika komwe angakumane nako tsiku lililonse.Opanga zida zoyambilira (OEMs) ayenera kuganizira za mapulasitiki opanda halogen, ndipo zopereka zosawoneka bwino ziyenera kukhala zolimba, zosagwira ntchito ndi malawi, komanso kupezeka mumitundu yambiri.Ngakhale mikhalidwe yonseyi iyenera kuganiziridwa, ndikofunikiranso kusunga chitetezo cha odwala pamwamba pamalingaliro.
Kusintha kupita ku Chipatala
Mapulasitiki oyambirira omwe anapangidwa kuti asatenthe kutentha mwamsanga anapeza malo m'dziko lachipatala, komwe kumafunikanso kuti zipangizo zikhale zolimba komanso zodalirika.Pamene mapulasitiki ochulukirapo adalowa m'chipatala, panabuka chofunikira chatsopano cha mapulasitiki azachipatala: chemical resistance.Zidazi zinali kugwiritsidwa ntchito pazida zomwe zidapangidwa popereka mankhwala ankhanza, monga omwe amagwiritsidwa ntchito pochiza oncology.Zipangizozi zinkafuna kukana mankhwala kuti zikhalebe zolimba komanso zokhazikika pa nthawi yonse yomwe mankhwalawa ankagwiritsidwa ntchito.
Dziko Lowawa la Mankhwala Opha tizilombo
Nkhani inanso yolimbana ndi mankhwala idabwera ngati mankhwala opha tizilombo towopsa kwambiri omwe amagwiritsidwa ntchito polimbana ndi matenda omwe amapezeka m'chipatala (HAIs).Mankhwala amphamvu omwe ali mu mankhwala ophera tizilombowa amatha kufooketsa mapulasitiki ena pakapita nthawi, kuwasiya kukhala osatetezeka komanso osayenerera azachipatala.Kupeza zinthu zosagwirizana ndi mankhwala kwakhala kovuta kwambiri kwa OEMs, popeza zipatala zimayang'anizana ndi malamulo owonjezereka kuti athetse ma HAI.Ogwira ntchito zachipatala amachotsanso zida zachipatala pafupipafupi kuti zikonzekere kugwiritsidwa ntchito, zomwe zimasokonezanso kulimba kwa zida zamankhwala.Izi sizinganyalanyazidwe;chitetezo cha odwala ndichofunika kwambiri ndipo zida zaukhondo ndizofunikira, chifukwa chake mapulasitiki omwe amagwiritsidwa ntchito m'chipatala ayenera kupirira kupha tizilombo toyambitsa matenda nthawi zonse.
Pamene mankhwala ophera tizilombo akuchulukirachulukira ndipo amagwiritsidwa ntchito nthawi zambiri, kufunikira kwa kukana kwa mankhwala muzinthu zomwe zimagwiritsidwa ntchito popanga zida zamankhwala kukukulirakulira.Tsoka ilo, sizinthu zonse zomwe zili ndi kukana kwamankhwala kokwanira, koma zimagulitsidwa ngati zimatero.Izi zimatsogolera kuzinthu zakuthupi zomwe zimabweretsa kusakhazikika bwino komanso kudalirika mu chipangizo chomaliza.
Kuphatikiza apo, opanga zida amayenera kuyang'anitsitsa bwino zomwe zimatsutsana ndi mankhwala zomwe zimaperekedwa.Mayeso omiza kwakanthawi kochepa samawonetsa molondola kutseketsa komwe kumachitika mukakhala muutumiki.Chifukwa chake, ndikofunikira kuti ogulitsa zinthu aziyang'ana pazida zonse zofunika akamapanga zinthu zomwe zimatha kupirira mankhwala ophera tizilombo.
Zida Za Halogenated mu Kubwezeretsanso
M'zaka zomwe ogula amakhudzidwa ndi zomwe zimapita kuzinthu zawo-ndipo odwala m'chipatala akudziwa bwino mapulasitiki omwe amagwiritsidwa ntchito panthawi yachipatala-OEMs ayenera kuganizira zomwe zipangizo zawo zimapangidwira.Chitsanzo chimodzi ndi bisphenol A (BPA).Monga momwe kulili msika wamapulasitiki opanda BPA m'makampani azachipatala, pakufunikanso kufunikira kwa mapulasitiki opanda halogenated.
Ma halojeni monga bromine, fluorine, ndi klorini amakhala otakataka ndipo amatha kubweretsa zotsatira zoyipa zachilengedwe.Zida zamankhwala zopangidwa ndi zinthu zapulasitiki zomwe zili ndi zinthuzi zikapanda kubwezeretsedwanso kapena kutayidwa moyenera, pamakhala chiwopsezo cha ma halogen omwe amatulutsidwa m'chilengedwe ndikukhudzidwa ndi zinthu zina.Pali nkhawa kuti zida zapulasitiki zokhala ndi halogen zimatulutsa mpweya wowononga komanso wapoizoni pamoto.Zinthuzi ziyenera kupewedwa m'mapulasitiki azachipatala, kuti muchepetse chiopsezo cha moto ndi zotsatira zoyipa zachilengedwe.
Utawaleza Wazinthu
M'mbuyomu, mapulasitiki opanda BPA anali omveka bwino, ndipo utoto unkangowonjezeredwa kuti upangire zinthuzo poyika chizindikiro kapena utoto monga momwe OEM idafunira.Tsopano, pakufunika mapulasitiki osaoneka bwino, monga aja opangira mawaya amagetsi.Ogulitsa zinthu omwe amagwira ntchito ndi mawaya opangira mawaya ayenera kuwonetsetsa kuti akuwotcha moto, kuti apewe kuyaka kwamagetsi ngati mawaya akusokonekera.
Cholemba china, ma OEM omwe amapanga zidazi amakhala ndi zokonda zamitundu zosiyanasiyana zomwe zitha kuperekedwa kumitundu inayake kapena pazokongoletsa.Chifukwa cha izi, ogulitsa zinthu ayenera kuwonetsetsa kuti akupanga zida zomwe zingagwiritsidwe ntchito kupanga zida zamankhwala mumitundu yeniyeni yomwe mitundu ikufuna, ndikuganiziranso gawo loletsa moto lomwe latchulidwa kale, komanso kukana kwamankhwala ndi kutsekereza.
Otsatsa zinthu ali ndi zinthu zingapo zofunika kukumbukira popanga chopereka chatsopano chomwe chitha kupirira mankhwala ophera tizilombo toyambitsa matenda komanso njira zoletsera.Ayenera kupereka zinthu zomwe zingakwaniritse miyezo ya OEM, kaya ndi mankhwala omwe ali kapena osawonjezedwa, kapena mtundu wa chipangizocho.Ngakhale izi ndizofunika kuziganizira, koposa zonse, ogulitsa zinthu ayenera kupanga chisankho chomwe chidzateteza odwala kuchipatala.
