Kangani kuchinja bhodhoro, rudzii rwakanaka

2024-10-08

Bhodhoro rinogadzirisa dambudziko remhuri dzakawanda: amai havagone kuyamwisa kubasa, unogona kusvina mukaka wezamu pachine nguva, uye mhuri inoshandisa bhodhoro kuyamwisa; Mwana anoyamwiswa nemukaka wehupfu haabviswi mubhodhoro, saka amai vanozonyanya kutarisisa kushandiswa uye kucheneswa kwebhodhoro, uye vakatotenga muchina wekuuraya utachiona kumba, asi imwe pfungwa inowanzo furatirwa naamai: bhodhoro harigone kushandiswa nekusingaperi!

Cherechedza: Nguva shoma yehupenyu hwebhodhoro imwedzi mina chete! Kutaura zvazviri, vanaamai vazhinji havana ruzivo rwekuchinja bhodhoro. bhodhoro, seamai vanotevera: bhodhoro remhuri rave richishandiswa kwegore nehafu, asi richiri kushandiswa, uye bhodhoro racho rinoraswa mushure mekuyeuchidzwa. Panyaya iyi, Wang Xiaoyan, mutevedzeri wechiremba mukuru wedhipatimendi rehutano reCapital Institute of Pediatrics, akakuyeuchidzai kuti bhodhoro repurasitiki remwana rinofanira kutsiviwa nenguva mushure memwedzi mitanhatu.

Ko nezvemamwe marudzi e Mabhodhoro eVachecheParizvino, mhando dzemabhodhoro akajairika ari pamusika mabhodhoro egirazi, mabhodhoro epurasitiki, mabhodhoro esilicone uye mabhodhoro esimbi isina ngura, ayo mabhodhoro epurasitiki anosanganisira: mabhodhoro ePP, mabhodhoro ePES, mabhodhoro ePPSU. Ngatitangei nekutaura nezvehupenyu hwemabhodhoro aya.

Kumabhodhoro egirazi: Zvinokurudzirwa kutsiva kamwe chete pagore.
Mabhodhoro egirazi evana akagadzirwa negirazi rinodzivirira kupisa kwakanyanya, chinhu chacho chakachengeteka, uye hazvisi nyore kuburitsa zvinhu zvinokuvadza kana zvapiswa. Wang Xiaoyan akataura kuti chero bedzi bhodhoro risingatyoki, rinogona kushandiswa kwenguva yakareba. Zvisinei, zvinofanira kucherechedzwa kuti nekuda kwekuti bhodhoro regirazi harina kusimba uye riri nyore kuchinja kuita yero, zvinokurudzirwa kuritsiva kamwe chete pagore, izvo zvinogona kuve nechokwadi chekuti chikafu chemwana chakachena uye chine hutano.

Pamabhodhoro epurasitiki evana, zvinhu zvakasiyana zvepurasitiki zvinogara kwenguva yakasiyana. Amai vanofanira kutarisa zvinhu zviri mubhodhoro pavanenge vachitenga bhodhoro.

① Kumabhodhoro epurasitiki akagadzirwa nezvinhu zvePP: zvinokurudzirwa kuatsiva kamwe chete pamwedzi mina yega yega.

Mabhodhoro evana ePP (polypropylene) akaderera pamutengo uye akareruka, anogona kutsungirira tembiricha yepamusoro ye110℃, asi hupenyu hwawo hupfupi, nyore kuoxidation, ngura isina kunaka, kujeka kwakashata, nguva refu ipfupi yekudzivirira tembiricha yepamusoro, haisi nyore kuchenesa, tsvina yemukaka iri nyore kusara, mabhakitiriya ari nyore kubereka, anonaka asi haana njodzi, saka kazhinji mwedzi mina yekutsiva kamwe chete, kwete kupfuura mwedzi mitanhatu! Nyanzvi yezveupfu hwemukaka payakaongorora mabhodhoro ePP, yakawana kuti mumamiriro ezvinhu akajairwa, nzira yavo yekutengesa yaive yekutengesa mabhodhoro akawanda pamwe chete, saka kana amai vakatenga rudzi urwu rwebhodhoro, rinofanira kutsiviwa nenguva.

② Yemwana wepurasitiki wePES mabhodhoroZvinokurudzirwa kuti uvatsive kamwe chete pamwedzi mitanhatu yega yega.

Mutengo webhodhoro remwana rePES (polyetholsulfone) wakakwira, asi rakareruka rinodzivirira kudonha, riri nyore kuchenesa, rinopisa kusvika 180℃, harisi nyore kuchenesa, harisi nyore kubvisa tsvina yemukaka, riri nyore kubereka mabhakitiriya, saka rinokurudzirwa kutsiva kamwe chete pamwedzi mitanhatu yega yega.

③ Kumabhodhoro epurasitiki evana akagadzirwa nezvinhu zvePPSU: zvinokurudzirwa kuatsiva kamwe chete pamwedzi mitanhatu kusvika misere yega yega.

Mabhodhoro evana ePPSU (polystyrene sulfone) anodhura zvakanyanya, asi akachengeteka zvakanyanya, anodzivirira kupisa kusvika 207 ° C, anogona kubikwa kakawanda pakupisa kwakanyanya, kuuraya utachiona hwemhepo, anodzivirira mishonga, anodzivirira acid nealkali, akareruka, anogona kutyoka, saka rudzi urwu rwebhodhoro rwakanaka kwazvo maererano nekuchengetedzeka, anodzivirira kupisa, anodzivirira hydrolysis uye anodzivirira kukuvadzwa, kana mamiriro epamba achibvumira, Zvinokurudzirwa kuti vanaamai vasarudze rudzi urwu rwebhodhoro revana vavo. Mabhodhoro ePPSU anogonawo kukamurwa kuita mabhodhoro ePPSU akajairwa uye mabhodhoro ePPSU anodzivirira kurutsa. Mabhodhoro ePPSU anodzivirira kurutsa anogona kuderedza zvinobudirira mweya unofemerwa nemwana paanonwa mukaka, kuderedza mukana wekubatwa nechando, kurutsa uye kurutsa mushure mekunge mwana anwa mukaka, uye mutengo uyu uchave wakanyanya kudhura, uye amai vanofanira kusanganisa zvinodiwa nemwana nesarudzo dzemari dzemhuri.

Kune mabhodhoro evana esilicone: Zvinokurudzirwa kutsiva kamwe chete pagore. Mutengo webhodhoro resilicone wakakwira, asi wakachengeteka uye hauna njodzi, kubata zvinyoro-nyoro kwakanaka, hakusi nyore kutyoka, kuri nyore kuchenesa, kuri nyore kuuraya utachiona, kunodzivirira kupisa kwakanyanya, hakusi nyore kukwegura, asi kuri nyore kunamira guruva, kunogona kushandiswa kwenguva yakareba. Zvisinei, bhodhoro pacharo rinogona kudyiwa, saka zvinokurudzirwa kuritsiva kamwe chete pagore, kuitira kuti chikafu chemwana chive chakachena uye chine hutano.

Uye zvakare, kana bhodhoro riine zvinotevera, rinofanirawo kutsiviwa nenguva:

● Pane mitswe kana kuti madonhwe emvura

● Ruvara rwebhodhoro rwachinja

● Pane maburi kana zvidimbu

● chikero chakasakara uye hachina kujeka

● ruvara rwemukaka rwasara zvakanyanya uye rwakaoma kuchenesa.
Chenjero: Usachinje bhodhoro kwenguva yakareba zvinogona kukuvadza zvakanyanya!
Mushure mekutaura hupenyu hwemabhodhoro aya, tichataura nezvekuti chii chingave chakaipa kana tikaomerera pakusatsiva mabhodhoro kwenguva yakareba?
Njodzi 1: Mabhodhoro epurasitiki anogona kukwegura kana achishandiswa, uye kana angocheneswa pakupisa kwakanyanya mushure mekukwegura, zvinhu zvinokuvadza zvinogona kuburitswa;
Njodzi 2: Bhodhoro rinoshandiswa kwenguva yakareba, zviri nyore kwazvo kuviga tsvina yemukaka. Makaka aya ane zvinovaka muviri zvakawanda uye anokwezva zvipembenene zvinobhururuka nemabhakitiriya zviri nyore. Kana ikashandiswazve, amai vemukaka bhodhoro Kubvisa utachiona hakuitwe, zviri nyore kukonzera kusagadzikana kwemudumbu remwana, manyoka, kuvimbiwa, nezvimwewo;
Njodzi 3: Bhodhoro rinoshandiswa kwenguva yakareba, rakawandisa, riri nyore kukwenya mwana;
Njodzi 4: Bhodhoro rinoshandiswa kwenguva yakareba rinogona kusabatsira mukaka wemwana. Bhodhoro diki harigone kugutsa zvinodiwa nemwana mukuru, izvo zvinogona kuita kuti mwana anwe mukaka kwenguva yakareba, mwana anogona kusanwa mukaka unotonhora, uye izvi hazvibatsiri kukura nekukura kwemwana kwenguva refu.
Izvi zvinoyeuchidza vanaamai: kana mwana anga achidya hupfu hwemukaka hwakafanana, kuchinjika kwemukaka kwakanaka kwazvo, asi kamwe kamwe rimwe zuva panobva pava nekusagadzikana kwakasiyana-siyana, kwakadai sekurutsa mukaka, manyoka, nezvimwewo, amai vanogona kutarisa kana bhodhoro remwana richifanira kutsiviwa.
