Ndi chitukuko cha anthu, kuchuluka kwa matayala akuchulukirachulukira, osati kungophatikiza zida zapaulendo monga njinga, magalimoto, magalimoto aulimi, komanso kuphatikiza zinthu zomwe zikubwera monga zoyenda makanda, zoseweretsa, magalimoto oyenda bwino, ndi zina zambiri. Zogwiritsa ntchito zosiyanasiyana zimakhala ndi zofunikira zosiyanasiyana pamatayala.Ndipo kuwala kwa magnesium oxide ndikowonjezera kofunikira komwe kumatha kukweza matayala.
Kodi kuwala kwa magnesium oxide ndi chiyani?
Magnesium oxide yowala ndi ufa woyera wa amorphous, wopanda fungo, wosakoma, komanso wopanda poizoni.Voliyumu yake ndi pafupifupi kuwirikiza katatu kuposa heavy magnesium oxide, ndipo ndi wamba wamba.Magnesium okusayidi yowala imakhala ndi ntchito zosiyanasiyana m'mafakitale monga matayala, labala, zoumba, zomangira, zitsulo, makampani opanga mankhwala, chakudya, mankhwala, etc.
Kodi ntchito ya kuwala kwa magnesium oxide mumatayala ndi chiyani?
Magnesium oxide yowala imatha kugwira ntchito zosiyanasiyana popanga matayala, monga:
- Scorch retarder: letsani mphira kuti asatenthedwe ndi kuphika panthawi yokonza.
- Vulcanization accelerator: fulumizitsa zomwe zimachitika pavulcanization ndikuwongolera magwiridwe antchito.
- Acid absorber: chepetsani zinthu za acid mu rabala, kupewa kukalamba ndi dzimbiri.
- Filler: onjezani voliyumu ndi kachulukidwe ka mphira, chepetsani mtengo.
- Kukana kutentha kwakukulu: kupititsa patsogolo bata ndi chitetezo cha matayala m'malo otentha kwambiri.
- Cholepheretsa moto: chepetsani liwiro loyaka komanso utsi wotulutsa matayala mukakumana ndi moto.
- Kukana kwa dzimbiri: kukana kukokoloka kwa zinthu zakunja monga chinyezi, mchere, asidi ndi alkali.
Kuphatikiza apo, kuwala kwa magnesium oxide kumakhalanso ndi ntchito inayake, yomwe imathandizira kuti matayala azigwira bwino ntchito, monga:
- Wonjezerani nthawi yotentha: onjezani kusinthasintha komanso kulimba kwa matayala.
- Yang'anirani zomwe zili mu rabara ndi ntchito yomatira: sinthani mawonekedwe a raba, mphamvu zolimba komanso kupindika kwamphamvu komanso zovuta zakutulutsa kutentha, chepetsani zolakwika.
- Pewani kuphulika kwa matayala ndi kutsekeka kwa gudumu: sinthani kudalirika ndi chitetezo cha matayala mukamathamanga kwambiri kapena kulemedwa kwambiri.
Ndiyenera kusamala chiyani ndikamagwiritsa ntchito kuwala kwa magnesium oxide?
Ngakhale kuwala kwa magnesium oxide kuli ndi zabwino zambiri pamatayala, zina ziyenera kutsatiridwanso mukamagwiritsa ntchito kupewa zovuta, monga:
- Chithandizo choteteza chinyezi: Magnesium oxide yopepuka ikatsitsidwa, imapangitsa kuti hydrochloric acid isasungunuke ndi zinthu zosungunuka m'madzi kukhala zokwera kwambiri, zomwe zimapangitsa matuza, diso lamchenga ndi zochitika zina.
- Kuwongolera kokwanira kwa Magnesium oxide: otsika kwambiri a magnesium oxide akhudza kulimba komanso kulimba kwa matayala;okwera kwambiri adzawonjezera kuuma ndi kuuma, kuchepetsa elasticity ndi ductility.
- Kuwongolera zomwe zili ndi calcium: kuchuluka kwa calcium kumapangitsa kuti matayala aphwanyike komanso kusweka.
- Kuwongolera Mlingo: Mlingo wocheperako umakulitsa kachulukidwe wolumikizana, zomwe zimabweretsa kufupikitsidwa kwanthawi yoyaka komanso nthawi yabwino yopumira, zomwe zimakhudza mphamvu yamatayala, kupsinjika kokhazikika komanso kuuma, kutalika;Mlingo wochuluka kwambiri umachepetsa kachulukidwe kakachulukidwe, Kutsogolera ku nthawi yayitali yowotcha komanso nthawi yabwino ya vulcanization, zomwe zimakhudza kukana kwa matayala, kukana kukalamba komanso kukana mafuta.
Choncho, posankha ndi kusunga kuwala magnesium okusayidi, muyenera kulabadira mwapadera kusankha mitundu yoyenera ndi specifications, kusunga youma ndi losindikizidwa chilengedwe, kuwonjezera malinga ndi gawo lolondola ndi njira, kuti tikwaniritse zotsatira zabwino za kuwala magnesium okusayidi. mu matayala.
