Magulu azinthu
Malinga ndi kapangidwe ka mankhwalawo, amagawidwa m'matewera a ana, matewera achikulire, matewera a ana / mapepala, ndi matewera / mapepala akuluakulu; molingana ndi mafotokozedwe ake, imatha kugawidwa m'magulu ang'onoang'ono (mtundu wa S), kukula kwapakatikati (M mtundu), ndi kukula kwakukulu (mtundu wa L). ) ndi mitundu ina yosiyana.
Matewera ndi matewera/mapadi amagawidwa m'makalasi atatu: zinthu zapamwamba kwambiri, zopanga zapamwamba, ndi zinthu zoyenerera.
kufunikira kwa luso
Matewera ndi matewera/mapadi ayenera kukhala aukhondo, filimu yapansi yosavunda iyenera kukhala yosawonongeka, osawonongeka, osapanga zolimba, ndi zina zotero, zofewa mpaka kukhudza, ndi zokonzedwa bwino; chisindikizocho chikhale cholimba. Gulu la elastic limamangidwa mofanana, ndipo malo okhazikika amakwaniritsa zofunikira zogwiritsira ntchito.
Muyezo wamakono wa matewera (mapepala ndi mapepala) ndiGB/T 28004-2011"Matewera (mapepala ndi ziwiya)", zomwe zimasonyeza kukula ndi mizere khalidwe kupatuka kwa mankhwala, ndi permeability ntchito (slippage kuchuluka, re-infiltration kuchuluka, kutayikira kuchuluka), pH ndi zizindikiro zina komanso zipangizo ndi ukhondo zofunika. . Zizindikiro zaukhondo zimagwirizana ndi zofunikira za dzikoGB 15979-2002"Ukhondo Wazinthu Zowonongeka Zaukhondo". Kuwunika kwa zizindikiro zazikulu ndi izi:
(1) Zizindikiro za thanzi
Popeza ogwiritsa ntchito matewera, matewera, ndi zosintha zosintha amakhala makamaka makanda ndi ana ang'onoang'ono kapena odwala osadziletsa, maguluwa ali ndi mphamvu zofooka za thupi ndipo amatha kutengeka, choncho mankhwalawo amafunika kukhala aukhondo komanso aukhondo. Matewera (mapepala, mapepala) amapanga malo a chinyezi komanso otsekedwa akagwiritsidwa ntchito. Zizindikiro zaukhondo kwambiri zimatha kuyambitsa kuchulukira kwa tizilombo toyambitsa matenda, potero kumayambitsa matenda m'thupi la munthu. Muyezo wa matewera (mapepala ndi mapepala) umanena kuti zizindikiro zaukhondo za matewera (mapepala ndi mapepala) ziyenera kutsata zomwe GB 15979-2002 "Miyezo Yaukhondo Pazinthu Zowonongeka Zowonongeka", ndi chiwerengero chonse cha mabakiteriya ≤ 200 CFU / g (CFU/g amatanthawuza pa gramu iliyonse Chiwerengero cha mabakiteriya omwe ali mu chitsanzo choyesedwa), chiwerengero chonse cha fungal colonies ≤100 CFU / g, coliforms ndi tizilombo toyambitsa matenda tizilombo toyambitsa matenda (Pseudomonas aeruginosa, Staphylococcus aureus ndi hemolytic Streptococcus) siziyenera. kuzindikirika. Panthawi imodzimodziyo, miyezo imakhala ndi zofunikira zokhwima pa malo opangira, mankhwala ophera tizilombo toyambitsa matenda ndi zimbudzi, ogwira ntchito, etc.
(2)Kulowa mkati
Kuchita kwa permeability kumaphatikizapo slippage, back seepage and leakage.
1. Kuchulukirachulukira.
Imawonetsa liwiro la mayamwidwe a mankhwalawa komanso kuthekera koyamwa mkodzo. Muyezowu umanena kuti kuchuluka kokwanira kwa matewera a ana (mapepala) ndi ≤20mL, ndipo kuchuluka kokwanira kwa matewera akuluakulu (mapepala) ndi ≤30mL. Zogulitsa zomwe zimakhala ndi kutsetsereka kochulukira sizimalowetsa mkodzo ndipo sizimalowa mkodzo mwachangu komanso moyenera, zomwe zimapangitsa kuti mkodzo utuluke m'mphepete mwa thewera (tsamba), zomwe zimapangitsa kuti khungu lanu linyowe ndi mkodzo. Zitha kuyambitsa kusapeza bwino kwa wogwiritsa ntchito, potero zimawononga mbali ya khungu la wogwiritsa ntchito, ndikuyika thanzi la wogwiritsa ntchito pachiwopsezo.
2. Kuchuluka kwa tsamba lakumbuyo.
Zimawonetsa kusungidwa kwa mankhwalawa pambuyo poyamwa mkodzo. Kuchuluka kwa kumbuyo kwakung'ono ndi kochepa, zomwe zimatsimikizira kuti mankhwalawa ali ndi ntchito yabwino potseka mkodzo, amatha kupatsa ogwiritsa ntchito kumverera kouma, ndi kuchepetsa zochitika za kuphulika kwa diaper. Kuchuluka kwa mkodzo wam'mbuyo ndi waukulu, ndipo mkodzo womwe umatengedwa ndi thewera umabwereranso pamwamba pa chinthucho, zomwe zimapangitsa kuti pakhale kukhudzana kwa nthawi yaitali pakati pa khungu ndi mkodzo wa wogwiritsa ntchito, zomwe zingayambitse matenda a khungu la wogwiritsa ntchito ndikuika pangozi kwa wogwiritsa ntchito. thanzi. Muyezo ukunena kuti kuchuluka koyenera kwa kuchuluka kwa kulowetsedwanso kwa matewera a ana ndi ≤10.0g, kuchuluka koyenera kwa kuchuluka kwa kulowetsedwanso kwa matewera akhanda ndi ≤15.0g, komanso kuchuluka koyenera kwa kuchuluka kwa kubwerezanso. kulowetsa matewera akuluakulu (zidutswa) ndi ≤20.0g.
3.Kutaya ndalama.
Imawonetsa kudzipatula kwa chinthucho, ndiye kuti, kaya pali kutayikira kapena kutayikira kumbuyo kwa chinthucho mutagwiritsa ntchito. Pankhani ya magwiridwe antchito, zinthu zoyenerera siziyenera kutayikira. Mwachitsanzo, ngati kuseri kwa thewera kwatuluka kapena kudontha, zovala za wogwiritsa ntchitoyo zimakhala zoipitsidwa, zomwe zimachititsa kuti mbali ina ya khungu la wogwiritsa ntchitoyo ilowerere mkodzo, zomwe zitha kuwononga khungu la wogwiritsa ntchito mosavuta. kuwononga thanzi la wogwiritsa ntchito. Muyezowu ukunena kuti mulingo woyenera kutayikira kwa matewera akhanda ndi akulu (zidutswa) ndi ≤0.5g.
Mapadi oyenerera, zoyamwitsa zoyamwitsa ndi zinthu zina siziyenera kukhala ndi madzi kapena kutayikira kuti zitsimikizire kuti sizikuwononga zovala panthawi yogwiritsidwa ntchito.
(3) pH
Ogwiritsa ntchito matewera ndi makanda, ana ang'onoang'ono, okalamba kapena anthu omwe satha kuyenda. Maguluwa ali ndi luso loyendetsa bwino khungu. Ngati matewera agwiritsidwa ntchito kwa nthawi yayitali, khungu silikhala ndi nthawi yokwanira yochira, zomwe zingayambitse kuwonongeka kwa khungu, motero kuyika thanzi la wogwiritsa ntchito pangozi. Choncho, ziyenera kutsimikiziridwa kuti acidity ndi alkalinity ya mankhwala sizingakwiyitse khungu. Muyezo umanena kuti pH ndi 4.0 mpaka 8.5.
