Ngokwewebhusayithi yeJiangsu yePhondo yoLawulo lokuLawula iMarike, nge-23 ka-Epreli, iJiangsu Textile Industry Association yakhupha ngokusemthethweni umgangatho weqela elithi "Polypropylene Melt blown Nonwoven Fabrics for Masks" (T/JSFZXH001-2020), eya kukhutshwa ngokusemthethweni nge-26 ka-Epreli. Ukuphunyezwa.
Umgangatho ucetywe yiJiangsu Fiber Inspection Bureau phantsi kwesikhokelo seJiangsu Market Supervision Bureau, kwaye wayilwa kunye neNanjing Product Quality Supervision and Inspection Institute kunye nabavelisi bamalaphu anyibilikisiweyo anxulumeneyo. Lo mgangatho ngumgangatho wokuqala wesizwe okhutshelwe amalaphu avuthelwe ngemaski avuthelwe ngamanzi. Isebenza ikakhulu kumalaphu avuthelwe yimaski anyibilike kukhuseleko lococeko. Yamkelwa ngamalungu eqela ngokuhambelana nesivumelwano kwaye yamkelwa ngokuzithandela luluntu. Ukubhengezwa kunye nokuphunyezwa komgangatho kuya kudlala indima ebonakalayo ekulawuleni ukuveliswa kunye nokusebenza kwamashishini amalaphu anyibilikisiweyo kunye nokuqinisekisa umgangatho wezinto ezisisiseko zeemaski. Kuyaqondwa ukuba imigangatho yeqela ibhekiselele kwimigangatho esekwe ngokudibeneyo ngamaqela asekuhlaleni asekwe ngokomthetho ukuhlangabezana neemfuno zeemarike kunye nokutsha kunye nokulungelelanisa nabadlali beemarike ezifanelekileyo.
Ilaphu elivuthelweyo elinyibilikayo lineempawu zobungakanani bepore encinci, i-porosity ephezulu kunye nokusebenza kakuhle kokucoca. Njengomathiriyeli ophambili wemveliso yemaski, imfuno yangoku inkulu kakhulu kunokubonelela. Kutshanje, iinkampani ezinxulumeneyo zitshintshele ekunyibilikiseni amalaphu avuthelweyo, kodwa azinalwazi lwaneleyo malunga nemathiriyeli ekrwada, izixhobo, kunye neenkqubo zokuvelisa ezisetyenziswayo. Ukusebenza kakuhle kwemveliso ye-melt blown ayiphezulu, kwaye umgangatho awukwazi ukuhlangabezana neemfuno zokuvelisa imaski.
Okwangoku, kukho imigangatho emibini efanelekileyo yoshishino lwamalaphu anyibilikayo anyibilikayo eTshayina, angala "Spun bond / Melt blown / Spun bond (SMS) Indlela yeNonwovens" (FZ / T 64034-2014) kunye ne "Melt blown Nonwovens" (FZ / T 64078-2019). Eyangaphambili ifanelekile kwiimveliso ze-SMS ezisebenzisa i-polypropylene njengeyona nto iphambili kwaye iqiniswe nge-bonding eshushu; le yokugqibela ifanele amalaphu angalukwanga aveliswa yindlela yokunyibilika. Ukusetyenziswa kokugqibela akukhawulelwanga kwiimaski, kwaye umgangatho ungobubanzi kuphela, ubunzima kwindawo nganye yeyunithi, njl.njl. Ukubeka phambili iimfuno, amaxabiso asemgangathweni ezalathisi eziphambili ezifana nokusebenza kakuhle kokucoca kunye nokungena komoya kuchazwe kunikezelo kunye imvumelwano yemfuno. Okwangoku, ukuveliswa kwamalaphu anyibilikayo ngamashishini kusekelwe ikakhulu kwimigangatho yeshishini, kodwa izikhombisi ezifanelekileyo nazo azilingani.
Umgangatho weqela le "Polypropylene Melt blown Nonwoven Fabrics for Masks" elikhutshwe ngeli xesha lijikeleza i-polypropylene inyibilika amalaphu angalukwanga avuthelweyo eemaski, echaza iimfuno zemathiriyeli ekrwada, ulwahlulo lwemveliso, iimfuno ezisisiseko zobugcisa, iimfuno ezizodwa zobugcisa, ukuhlolwa kunye neendlela zokugweba, kunye nemveliso. logo ibeka iimfuno ezicacileyo. Iimpawu eziphambili zezobugcisa zemigangatho yeqela zibandakanya ukusebenza kakuhle kokucoca, ukuhluzwa kwebhaktheriya, amandla okuphula, izinga lokuphambuka kobunzima kwindawo nganye, kunye neemfuno zomgangatho wokubonakala. Umgangatho uchaza oku kulandelayo: Okokuqala, imveliso ihlelwa ngokwenqanaba lokuhluza imveliso, eyahlulwe ngamanqanaba ama-6: KN 30, KN 60, KN 80, KN 90, KN 95, kunye ne-KN 100. kukuchaza imathiriyeli ekrwada esetyenziswayo, ekufuneka ihlangabezane neemfuno ze-“Special Plastic Melt-Blowing Material for PP” (GB/T 30923-2014), ukunciphisa ukusetyenziswa kwezinto ezinobuthi kunye nobungozi. Okwesithathu kukubeka phambili iimfuno ezithile zobuchule bokuhluza kwenxalenye kunye nempumelelo yokucoca ibhaktheriya ehambelana namanqanaba ahlukeneyo okuhluza ukufezekisa iimfuno zeentlobo ezahlukeneyo zeemaski zelaphu elinyibilikayo.
Kwinkqubo yokuqulunqa imigangatho yeqela, okokuqala, ukuthobela umthetho kunye nemimiselo, landela imigaqo yokuvuleleka, ukungafihli, kunye nobulungisa, kwaye ufunxe amava okuvelisa, ukuhlola, kunye nokulawula amalaphu anyibilikayo kwiPhondo laseJiangsu, kwaye ngokupheleleyo. qwalasela ubugcisa obuphambili kunye noqoqosho olunokwenzeka ngokubanzi. Iimfuno, ngokuhambelana nemithetho yesizwe, imimiselo kunye nemigangatho enyanzelekileyo, ziye zamkelwa ziingcali kubenzi abakhulu bamalaphu anyibilikisiweyo, ukuhlolwa. amaziko, imibutho yoshishino, iiyunivesithi kunye namaziko ophando lwenzululwazi kwiphondo, nto leyo enceda indima yomgangatho wokhokelo kunye nommiselo. Okwesibini kukwenza umsebenzi omhle wokudibanisa ngokufanelekileyo imigangatho yeemveliso zengubo ezinyibilikayo kunye nemigangatho yeemaski ezikhuselayo, ezinokudlala indima efanelekileyo ekulinganiseni, ekuphuculeni nasekulungiseni iqela lamashishini kwimbono yobugcisa.
Ukukhutshwa komgangatho weqela kuya kudlala indima yomgangatho weqela "ukukhawuleza, ubhetyebhetye kwaye uhambele phambili", ukunceda imveliso yelaphu elinyibilikayo kunye nokusebenza kwamashishini ukuqonda ngokuchanekileyo kunye nokuqonda izikhombisi eziphambili zelaphu elinyibilikayo lemaski, ukuphucula imveliso. imigangatho, kunye nokuvelisa ngokuhambelana nemithetho nemimiselo Ukubonelela ngenkxaso yobugcisa esebenzayo yokulawula ulungelelwaniso lwentengiso lwamalaphu anyibilikisiweyo avuthelweyo kunye nokuqinisekisa umgangatho weemveliso zothintelo lobhubhane. Okulandelayo, phantsi kwesikhokelo se-Provincial Market Supervision Bureau, iProvincial Fiber Inspection Bureau iza kusebenza noMbutho wePhondo woShishino lweMilaphu ukutolika nokupapasha imigangatho kunye nokwazisa ngakumbi ulwazi olusemgangathweni olunxulumene namalaphu anyibilikisiweyo. Kwangaxeshanye, iya kwenza umsebenzi omhle ekubhengezeni nasekuphumezeni imigangatho, iqeqeshe amashishini amakhulu emveliso kunye nabaphathi abasezantsi kwiphondo, kunye nokukhokela ngakumbi ukuveliswa nokubekwa kweliso kwamalaphu anyibilikisiweyo.
