Package:750 G / Bhodhoro, Hore makumi maviri mabhodhoro mune imwe bhokisi bhokisi, 180kg / mbiya, kana sekutarisana nevatengi chikumbiro.
Destodur re ndeye inonyanya kushanduka-inobatanidza mumiriri, Inoshandiswa mumakwikwi akagadzirwa neHydroxyl Polyurethane, zvakasikwa kana synthetic rarber,
Iyo ine yakanaka kusungwa Simba muSharber uye Cab Inoshandiswa muResin, Antioxidant, plastictizing mumiririri, kumanikidzwa-anonzwa etc.
Inogona kushandiswa seanoyambuka pachinzvimbo cheBayer's Demodur re
Maviri-chikamu chinonamatira chinofanira kushandiswa mukati menguva inoshandiswa mushure mekuisa mune re.
Kureba kwenguva inoshanda hakuna kuwirirana nemutengo wezvemukati mezvinamatire,
Kana iri pedyo nenguva inoshanda, kazhinji maawa mashoma kana rimwe zuva rekushanda, kunamatira kunova kwakaoma kushanda, uye viscosity inokwira munguva pfupi.
Pakupedzisira, inova isingachinjiki jelly. 100 mhando inonamatira, hydroxyl polyurethane (polyurethane account yekutenderedza 20%), regone 4-7. Chloroprene Rubber (Rubber Akaunti yeKutenderedza 20%), Re inoita 4-7.
Destodur re inonyanya kushandiswa seyakaomesa kana kuyambuka mumugwagwa wakasiyana-siyana purlyurethane. Zvishandiso zvinosanganisira:
1. Coatings: dedomitur re inowanzo shandiswa mukuumbwa kwejasi rakakwirira-pericings, kusanganisira maindasitiri uye emaindaniso ekutakura. Iyo inovandudza kusimba, kuramba kwemakemikari uye mamiriro ekunze ekurwisa zvipfeko.
2. Kunamatira: Inoshandiswa mukugadzirwa kwePolyurethane zvinonamira kuti vavandudze kushamwaridzana uye kuramba kune zvinhu zvakatipoteredza.
3..
4. Foam: Mune zvimwe zviitiko, zvinogona kushandiswa kuburitsa chinja kana kuomarara polyurethane foam, ichibatsira kuvandudza maitiro ayo ekugadzira uye kugadzikana.
5. Elastomers: Iyo inoshandiswawo mukuumbwa kwePolyurethane Elasmomers, inoda chaizvo maitiro ekuita sekushanduka-tsika, elasticity, uye abrasion kuramba.
Ndokumbirawo kuchengetedzeka mugomba repakuvamba rakavanzika pasi pemakore makumi maviri nematatu, zvigadzirwa zvinogona kuchengetedzwa chakagadzikana kwemwedzi gumi nemaviri.
Inonzwa zvakanyanya zvakanyanya kunaka; Iyo ichave inogadzira carbon dioxide uye insoluble urea mukuita nemvura.
Kana kuratidzwa kwe teh mhepo kana mwenje, ichakurumidza kuita shanduko, asi basa rinoshanda harina kukanganiswa.
Kuti iite nenzira yakakodzera destour re, tevera izvi nhungamiro:
1. Tembiricha: Chitoro Destodur Re munzvimbo inotonhorera, yakaoma. Yakakurudzirwa yekuchengetedza tembiricha kazhinji pakati pa15 ° C uye 25 ° C (59 ° F uye 77 ° F). Ngwarira kuratidzwa nekunyanyisa kupisa.
2. Ita shuwa kuti mudziyo wakagadzirwa nemidziyo inoenderana yekudzivirira maitiro.
3. Ventilation: Chitoro munharaunda yakanyatsonaka yekudzikisa vapor kuwanda. Dzivisa kuchengetedza padyo nemoto kana kupisa masosi.

5. Kuchengetedza Kwangwara: Ita kuti nzvimbo dzekuchengetedza dzakashongedzwa nematanho akakodzera ekuchengetedza, sekuti sedzimanikidzo matanho ekuchengetedza uye nekudzivirira kwemidziyo yako
6. Zuva rekubuda Shandisa chigadzirwa mukati menguva yakatarwa yemhedzisiro yemhedzisiro yakanaka.
750 G / Bhodhoro kana 50 KG / Drum kana 180 KG / Drum kana Kubva pane zvinodiwa zveVatengi.
* Tinogona kugovera mhando dzakasiyana dzekutakura zvichienderana nevatengi zvevatengi.
* Kana huwandu hushoma, tinogona kutumira nemhepo kana dzenyika dzenyika, dzakadai saFedEx, DHL, tnt, tnt, ems uye dzakasiyana siyana dzekutakura nzvimbo dzinokosha.
* Kana huwandu hukuru, tinogona kutumira gungwa kuGungwa kugadza.
* Kunze kwezvo, isu tinokwanisa kupawo mabasa akakosha zvichienderana nezvinodiwa nevatengi uye zvigadzirwa 'zvivakwa.
Ehe, Destodur re, sevamwe maOCOCANATITATES, inogona kukuvadza kuvanhu kana isina kubatwa nemazvo. Heano dzimwe pfungwa dzinokosha nezvezvingaitika zvaro zvehutano:
1. Inhalation: Kuratidzwa kweSocyanate Vapors kunogona kutsamwisa system yekufema uye kunogona kukonzera iyo airway sensitization inotungamira kune asthma-sezviratidzo mune vamwe vanhu.
2.. Kwenguva refu kana kudzokorora kusangana kunogona kukonzera allergic ganda rezita.
3. Ziso rekutarisana: Inogona kukonzera zvakakomba ziso kutsamwisa uye kukuvara. Pfeka ziso rokudzivirira kana uchibata zvinhu izvi.

5. Kuchengetedza Kuchengetedza: Paunenge uchishanda neDestodur Re, Zvakakodzera Zvekudzivirira Midziyo (PPE) inofanira kushandiswa, kusanganisira magurovhosi, gggles uye kudzivirirwa kwekufema kana zvichidikanwa. Ita shuwa kuti nzvimbo yebasa yakanyatsovhurwa kuti ideredze kuratidzwa.
Kana uchitakura destomitour re, chaicho nzira dzekudzivirira dzinofanira kuteverwa kuti uve nechokwadi chekuchengetedza uye kuyananisa kutevedzera. Heano mamwe mafungiro akakosha kuti afunge nezve:
1. Label: Ita shuwa midziyo inonyorwa nemazvo sekutonga zvinodiwa. Labels inosanganisira njodzi zviratidzo uye kubata mirairo.
2. Mudziyo unofanirwa kusimbiswa kuti udzivise kubhururuka uye kuratidzwa kunonyorova.

4. Ventilation: Ita shuwa kuti mota yekutakura inovhara zvakanaka kuti ideredze kuunganidzwa kwemapuronde.
5. Kuchengetedza Kwemunhu (PPE): Vashandi vanopinda mukufambisa vanofanirwa kupfeka yakakodzera ppe, kusanganisira magurovhosi, uye, kana zvichidikanwa, zvichidzivirirwa.
6. Maitiro emergency: iva anoziva nemaitiro emergency kana akashatiswa kana kubhururuka panguva yekufambisa. Gadzirira zvinhu zvekudzora zvave kugadzirira.
