Formaldehyde (HCHO) chinhu chisina ruvara, chine pungent strongly pungent organic compound (VOC) chiri gasi patembiricha yemumba uye chinonyungudika nyore nyore mumvura. Chinhu chakakosha mukugadzirwa kwemaindasitiri akawanda uye maitiro ekugadzirisa muviri, chinoshandiswa zvakanyanya muminda inotevera: maresini ekugadzira (akadai seurea formaldehyde resins, phenolic resins), manamati, mapurasitiki, machira ekupedzisa, nezvimwewo.
Formaldehyde inorongwa seboka rekutanga rekenza (rinoonekwa sekenza kuvanhu) neWorld Health Organization (WHO) neInternational Agency for Research on Cancer (IARC), uye njodzi dzayo dzinoonekwa zvakanyanya mu:
①Kusangana nechirwere kwenguva pfupi:
Kutsamwiswa: Kubata maziso zvakananga kunogona kukonzera kutsvuka nekuzvimba, kunzwa kupisa pahuro, kusawirirana neganda, nezvimwewo.
Zviratidzo zvekufema: zvinotungamira mukukosora, kusimba kwechipfuva, kuwedzera kweasthma, nezvimwewo.
②Kusangana nechirwere kwenguva refu:
Njodzi yekenza: Kufema formaldehyde kwenguva refu kunogona kukonzera nasopharyngeal carcinoma, leukemia, nezvimwewo.
Chepfu isingaperi: inokuvadza masoja emuviri, tsinga, uye inonyanya kukuvadza vakadzi vane pamuviri, vana, nevakwegura.
Mushonga wedu weAldehyde Scavenger unoshandiswa kubvisa formaldehyde neacetaldehyde zvakasara kubva mumapolymers,inonyanya kukodzera kubvisa acetaldehyde kubva kuPET kuti ienderane nezvinodiwa zvepakeji yechikafu nechinwiwaYakakodzerawo kubvisa formaldehyde neacetaldehyde kubva mumaresini eacetate, manamati, uye pendi.
PET (polyethylene terephthalate) chinhu chinoshandiswa zvakanyanya mumabhodhoro ezvinwiwa. Padzidziso, PET chaiyo haina formaldehyde, asi zvinhu zvinotevera zvinogona kukonzera kuti ive nehuwandu hushoma hwe formaldehyde:
① PET inogona kuora zvishoma panguva yekugadzirisa kupisa kwakanyanya (sekunyunguduka kwemvura), zvichiburitsa huwandu hushoma hwe formaldehyde.
② Zvinhu zvinoshandiswa mukugadzira PET, zvakaita sema antimony compounds, zvinogona kukonzera mhedzisiro yemuviri uye kugadzira formaldehyde.
③ Zvimwe zvinhu zvinopenda kana zvinhu zvinobatsira pakugadzirisa zvinogona kuora nekuburitsa formaldehyde kana paine tembiricha yakakwira kana chiedza.
Tibatei! Tichapindura mukati memaawa makumi mana nemasere.
