Yadda ake sarrafa lokacin farawa na yashi mai saurin jujjuyawar yashi a ƙasan yanayin zafin jiki

Anyi nazarin alaƙar da ke tsakanin lokacin amfani da yashin furan resin, lokacin sakin mold da ƙarfi a ƙarƙashin yanayin yanayin zafi, kuma ya ƙaddara zafin yashi da ya dace da raunin warkar da wakili don jagorantar samar da bitar.

Tarihi

Gurasar da ba ta yin burodi ba ta da ƙanƙanta kuma mai ƙarfi, mai sauƙin sarrafawa, kuma tana da madaidaicin madaidaicin simintin gyare-gyare. Sabili da haka, an yi amfani da tsarin yashi ba-gasa na yanzu don jefa simintin ƙarfe iri-iri, kamar kayan aikin injin da ake buƙata don injinan da injin iskar gas da ake amfani da su wajen gina jirgin ruwa. Kuma ana iya samar da wasu simintin ƙarfe ta hanyar aikin yashi mai taurin kai. A zamanin yau, saurin haɓaka sarrafa sarrafa kansa ta kwamfuta ya hanzarta haɓakawa da aikace-aikacen fasahar yashi resin.

Koyaya, yashi furan furanni yana da nasa gazawa. Lokaci mai amfani, lokacin sakin mold da ƙarfin ƙarshe yana shafar ƙwarai ta canje -canje a yanayin zafi da zafi, wanda zai iya haifar da rashin kwanciyar hankali cikin sauƙi kuma yana shafar samar da bitar. Dangane da kayan simintin da kamfanin ke amfani da su, wannan takarda tana nazarin tsarin warkarwa na furan resin da benzenesulfonic acid curing wakili a cikin nau'ikan daban -daban a ƙarƙashin yanayin yanayin zafi, yana ƙayyade mafi kyawun rabo, kuma yana bincika yanayin ƙwanƙwasawar ƙirar katako da ƙirar resin ƙarfe. akan wannan tushe. , A gabatar da hanyar hanzarta sakin katako don jagorantar samar da bita.

Binciken gwaji

Wannan labarin yana amfani da resin furan, wakilin warkarwa na benzene sulfonic acid da yalwar yashi wanda kamfanin ke amfani da shi a wurin azaman kayan gwaji

Kayan aiki: ma'aunin lantarki, mahaɗa ta atomatik, gwajin matsawa, ma'aunin zafin jiki da zafi, ma'aunin zafi da sanyio, agogon gudu. Zazzabi na yanayi shine 5 ℃, zafi na yanayi shine 30%, kuma zafin yashi shine 15 ℃. Auna 1000g na yashi tare da ma'aunin lantarki. Matsayin ƙari na resin shine 0.8% da 1.0% na nauyin yashi. An ƙara wakili na warkarwa zuwa 30%, 35%, 40%, 45%, 50%na nauyin resin, bi da bi. Gwajin orthogonal ya sa block40mm × 40mm Molding sand test block. A lokaci guda, yi rikodin lokacin aiki, lokacin sakin mold da ƙarfin matsa lamba na 24h.

Dangane da buƙatun samarwa akan-site, akwai buƙatun masu zuwa don gyaran yashi:

• Yakin da ya keɓewa dole ne ya kula da wani ƙarfi na ƙarshe (ƙaramin simintin ≥2.0MPa, manyan simintin ≥3.0MPa) don rage nakasa na ainihi da hana haɗa yashi a cikin simintin gyare -gyare.
• Dole ne a tabbatar da lokacin aikin da ake buƙata don sauƙaƙe sanya jarin ƙarfe, baƙin ƙarfe mai sanyi da ƙaramin aiki.
• Domin tabbatar da samar da ingantaccen aiki a kan yanar gizo, babban lokacin fitarwa yakamata ya zama ɗan gajeren lokaci don haɓaka ingantaccen samarwa.
• A cikin yanayin biyan buƙatun samarwa, adadin daɗaɗɗen da aka ƙara yakamata ya zama mafi ƙanƙanta, wanda ba kawai yana adana farashi ba, har ma yana rage iskar gas ɗin da ake samu ta hanyar ƙona mai ƙyallen ƙwayoyin cuta yayin zubar, yana inganta ingancin simintin gyare -gyare, da kuma kare muhalli.

Dangane da abubuwan da ke sama, mafi kyawun rabo na kayan ruwa na yashi da aka ƙera yashi shine resin 1.0% (lissafin nauyin yashi), wakilin curing 30% (lissafin resin); Mafi kyawun ruwa-kayan rabo na yashi mai ƙona zafi shine resin 1.0% (lissafin nauyin yashi)), wakili mai warkarwa 45% (lissafin resin).

Bugu da ari, la'akari da bambanci a lokacin fitarwa tsakanin ƙirar katako da ƙirar ƙarfe da aka samar akan rukunin yanar gizon, a kan gwajin da ke sama, an yi amfani da akwatin katako da babban akwatin ƙarfe don shirya samfura, da ƙarfin matsawa. an auna kowane 1h, kuma an yi rikodin yanayin canjin ƙarfi na farkon 6h da 24h. Ƙarfin ƙarshe

Hakanan a ƙarƙashin yanayin 5 ℃, lokacin da aka ƙara wakilin resin da curing a cikin wani gwargwado:

• Tsarin ƙirar ƙirar katako yana ɗaukar kimanin awanni 2 zuwa 3 don fitar da kwandon daga ƙirar (1.5MPa), kuma ƙirar ta taurare don samun isasshen ƙarfi ba tare da nakasa ba; ƙirar ƙarfe tana ɗaukar awanni 5 don ɗauka, kuma ana iya fitar da ɓangaren ciki da wuri. Gabaɗaya ya taurare, ɓarna na ɓarna zai faru, kuma ƙarfin ƙarshe daidai yake, kusan 3MPa.
• Kawai ƙara ƙimar acidity na wakili na warkarwa ba zai iya haɓaka saurin maƙarƙashiya da takaita lokacin sakin mold ba.

Dangane da wannan yanayin taurin kai, samarwa kan-site na iya tsara yadda yakamata bisa ga tsarin farawa daban-daban don gujewa farkon farawa. Ƙarfin isasshen ƙarfi na yashi a cikin gindin zai haifar da nakasa da fasawa. Babban ƙirar ƙirar tana da ƙarfi mai ƙarfi kuma an haɗa ta sosai da ƙirar. , Yana da wuyar fara ƙirar, yana haifar da ƙarancin ingancin ƙasa da jinkirta samarwa akan-site.

Kammalawa

A cikin yanayin ƙarancin zafin jiki, lokacin da ake amfani da resin furan da wakili na warkar da sulfon acid na benzene azaman masu ɗaurewa, akwai ƙarshen gwaji guda uku kamar haka:

• Mafi kyawun kayan ruwa don yashi da aka ƙera na injin shine resin 1.0% (lissafin nauyin yashi), wakilin curing 30% (lissafin resin); mafi kyawun ƙari na kayan ruwa don yashi mai ƙona zafi shine resin 1.0% (lissafin nauyin yashi), yana magance Wakili 45% (lissafin resin).
• Sauran yanayin ba su canzawa. Kawai ƙara yawan acidity na wakili na warkarwa ba zai iya rage lokacin sakin mold ɗin ba. Za'a iya hanzarta halayen ciki da taurin ta hanyar ƙara yawan zafin jiki na ƙirar, zafin baƙin ƙarfe mai sanyi da kayan aiki.
• Lokacin da yanayin ya kasance iri ɗaya, lokacin fitarwa na ƙirar katako yana ragu sosai idan aka kwatanta da ƙirar ƙarfe, kuma tsohon shine 1/2 na ƙarshen.

Da fatan za a adana tushe da adireshin wannan labarin don sake bugawa: Yadda ake sarrafa lokacin farawa na yashi mai saurin jujjuyawar yashi a ƙasan yanayin zafin jiki
