Tua 90% Ntawm Tus Kab Mob Coronavirus Tshiab Hauv 10 feeb, Hong Kong Polytechnic University tau tsim cov khoom siv tshuaj tiv thaiv kab mob 3D

Pab pawg tshawb fawb hauv Hong Kong Polytechnic University tau ua tiav lub ntiaj teb' thawj cov khoom siv tshuaj tiv thaiv kab mob 3D luam ntawv uas tuaj yeem tua ntau dua 90% ntawm tus kabmob tshiab no thiab cov kab mob thiab cov kab mob feem ntau hauv 10 feeb.

Nws tau tshaj tawm tias cov khoom siv 3D luam ntawv no yuav siv rau hauv lub qhov rooj ntawm ze li 100 Sanwu lub tsev uas tsis muaj kev tswj hwm hauv Shenshui Port. Pab neeg tshawb fawb tseem tab tom koom tes nrog lub tuam txhab txhaj tshuaj molding los tsim cov khoom loj thiab dav siv hauv cov chaw pej xeem xws li elevator nyees khawm thiab tes. Muab kev txhawb nqa kev tiv thaiv kab mob sib kis rau cov zej zog, thiab npaj tsim cov tsev noj mov muab faib tawm cov phiaj xwm thiab cov xov tooj ntawm tes.

Hauv kev sim cov khoom siv los ntawm Hong Kong Polytechnic University hauv xyoo dhau los, suav nrog ib puag ncig uas tuav lub thawv rov ua dua tshiab thiab khawm of elevator tau tsim, pom tias cov khoom tsis raug puas tsuaj, thiab tsis muaj kab mob ntsws tshiab. kuaj tau tus kab mob. Kev ua tau zoo ntawm cov tshuaj yuav maj mam poob qis tom qab 3 xyoos ntawm kev siv. .

Hong Kong Polytechnic University tau ua tiav ib qho kev tiv thaiv kab mob 3D luam ntawv uas tuaj yeem siv rau cov nyees khawm elevator.

Cov khoom tseem ceeb ntawm cov khoom siv yog cob, thiab cov tshuaj tiv thaiv kab mob xws li cationic compounds ntxiv rau tho lub cell membrane ntawm tus kab mob thiab rhuav tshem nws cov qauv; tsuav yog tus kab mob los yog kab mob muaj cov kab mob ntawm tes, txawm tias muaj qhov sib txawv, nws tuaj yeem raug tua.

Associate Professor Lu Junyu ntawm PolyU' Department of Textiles and Clothing, uas yog tus coj pab neeg, tau taw qhia tias cov txheej txheem ntxuav tus kheej ntev ntev ntawm kev ua lag luam tsuas yog siv sijhawm li 1 txog 2 lub hlis, thiab kev tu txhua hnub yuav ua kom lub tev tawm ntawm qhov chaw ntawm cov khoom, thiab cov nqi kho mob kuj siab. Cov khoom siv no muaj zog dua thiab ua haujlwm zoo. Ntxiv nrog rau cov resin yog ib qho nyuaj thiab tsis yooj yim rau kev puas tsuaj, kev sim kuaj tau kuj tau lees paub tias cov khoom tuaj yeem tua 70% ntawm tus kabmob tshiab thiab lwm yam kabmob uas muaj sia nyob ntawm nws qhov chaw hauv 2 feeb, thiab tus nqi tiv thaiv tsis pub dhau 10. feeb siab dua. Txog li 90%, yuav luag tag nrho cov kab mob thiab cov kab mob ntawm qhov chaw tuaj yeem tua tsis pub dhau 20 feeb, thiab cov khoom tuaj yeem tua ntau dua 84% ntawm cov kab mob hauv 10 feeb tom qab siv 3 xyoos.

Tsis tas li ntawd, txij li cov tshuaj tua kab mob ntawm cov khoom yog embedded es tsis yog ib txheej, txawm tias nws yog ntxuav nrog tshuaj tua kab mob xws li tshuaj bleach, nws anti-virus nyhuv yuav tsis cuam tshuam.

Lu Junyu kuj tau taw qhia tias 3D tshuab luam ntawv tuaj yeem siv rau kev tsim khoom, vim nws yuav tsum tsim cov duab sib txawv thiab muaj cov yas siab. Nws tuaj yeem siv dav hauv cov chaw pej xeem los pab txhawb kev tiv thaiv kev sib kis rau zej zog. Piv txwv li, pab neeg no tau ua cov khoom siv rau hauv cov khoom siv rov ua dua tshiab thiab cov chav dej hauv xyoo dhau los. Lub qhov rooj tuav tiv thaiv, khawm of elevator thiab Braille boards, thiab lwm yam, yog siv hauv Hong Kong Wetland Park, siv cov khaub ncaws rov ua dua tshiab, thiab lwm yam. Kev sim tsis tu ncua tsis pom tus kabmob tshiab thiab cov kab mob xws li E. coli thiab Streptococcus aureus, thiab muaj. tsis muaj kev puas tsuaj. Pab neeg no yog patenting thev naus laus zis rau kev lag luam siv.

Pab neeg no tau caw los ntawm Sham Shui Po District Office los ua lub qhov rooj tiv thaiv npog rau ntau tshaj 100 lub tsev tsis muaj kev tswj hwm hauv cheeb tsam, thiab nruab rau ntawm lub qhov rooj uas cov neeg nyob niaj hnub siv los pab txo tus nqi ntawm lub tsev sab hauv. pheej hmoo kis tus kab mob.

Lu Junyu tau hais tias tus nqi ntawm cov khoom siv tshiab no tsis siab thiab nws yog qhov ruaj khov. Lub elevator khawm yuav siv sij hawm luv luv los ua, thiab nws ntseeg tias nws tuaj yeem siv dav sai li sai tau. 10 lub elevator nyees khawm tuaj yeem ua nyob rau hauv li 10 feeb los ntawm 3D luam ntawv, thiab cov khoom siv nqi tsuas yog 10 yuan. Nws kuj tau hais tias tam sim no pab pawg tshawb fawb tab tom koom tes nrog cov tuam txhab txhaj tshuaj molding, vam tias yuav tsim cov khoom loj thiab siv dav hauv cov tsev kawm ntawv theem pib thiab theem nrab, cov chaw kho mob, thiab kev thauj mus los rau pej xeem. Kuj tseem muaj cov phiaj xwm tsim cov tsev noj mov muab faib ua pawg, rooj sib tham hauv xov tooj, thiab lwm yam. Daim ntawv thov hauv kev tsim vaj tsev.
