1.Ukucokisa iplastiki
Inkcazo yePlasitiki: Isenzeko apho irabha itshintsha isuka kwielastiki iye kwiplastiki phantsi kweempembelelo zezinto zangaphandle ibizwa ngokuba yiplastiki.
(1)Injongo yokusulungekiswa
a.Yenza irabha ekrwada ifikelele kwiqondo elithile leplastikhi, elilungele izigaba zamva zokuxuba kunye nezinye iinkqubo
b.Hlanganisa iplastiki yerabha eluhlaza kwaye uqinisekise umgangatho wezinto zerabha
(2)Ukumiselwa kwekhompawundi yeplastiki efunekayo: I-Mooney engaphezulu kwama-60 (ithiyori) iMooney ngaphezu kwama-90 (okwenene)
(3)Umatshini wokucoca iplastiki:
a. Vula ilitye
Iimpawu: Ubuninzi bomsebenzi ophezulu, ukuveliswa kwemveliso ephantsi, iimeko zokusebenza ezimbi, kodwa ziguquguqukayo, kunye notyalo-mali oluphantsi, kwaye zifanelekile kwiimeko ezinotshintsho oluninzi Umlinganiselo wesantya seedramu ezimbini zomatshini ovulekileyo: ngaphambili ukuya ngasemva (1: 1.15) -1.27)
Iindlela zokusebenza: Indlela yokucokisa iplastiki, ukusonga iplastiki yokucolwa, indlela yokukhwela isakhelo, indlela yokwenza imichiza yeplastiki.
Ixesha lokusebenza: Ixesha lokubumba akufanele lidlule imizuzu engama-20, kwaye ixesha lokupaka kufuneka libe yi-4-8 iiyure.
b.Umxhubi wangaphakathi
Iimpawu: Ukusebenza kakuhle kwemveliso, ukusebenza lula, ukuqina kwabasebenzi abaphantsi, kunye neplastiki efanayo. Nangona kunjalo, amaqondo okushisa aphezulu angabangela ukuhla kwezinto ezibonakalayo kunye nomatshini wezinto zerabha
Indlela yokusebenza: Ubungakanani → Ukutya → Ukufakwa kwePlastiki → Ukukhupha → Ukubuyisela umva → Ukucofa → Ukupholisa nokukhulula → Ugcino
Ixesha lokusebenza: 10-15 imizuzu Ixesha lokupaka: iiyure ze-4-6
(4)Rhoqo irabha eyenziwe ngeplastiki
Izixhobo zerabha ezisoloko zifuna ukubunjwa ziquka i-NR, i-NBR eqinile, irabha eqinileyo, kunye nezo zinereyithingi ye-Mooney ye-90 okanye ngaphezulu.
2.Ukuxuba
Inkcazo yokuxuba kukongeza izongezo ezahlukeneyo kwirubha ukwenza irabha edibeneyo
(1)Vula umxube wokuxuba
a.Ukusonga i-roller: Songa irabha ekrwada kwirola yangaphambili kwaye ube nenkqubo yokufudumeza emfutshane yemizuzu emi-3-5.
b.Inkqubo yokutya: Yongeza izongezo ezifuna ukudityaniswa ngendlela ethile. Xa ukongeza, nikela ingqalelo kumthamo weglue eqokelelweyo. Okuncinci kunzima ukuxuba, ngelixa ngaphezulu kuya kuqengqeleka kwaye kungabi lula ukuxuba
Ulandelelwano lokutyisa: irabha ekrwada → i-ejenti esebenzayo, i-ejenti yoncedo → isulfure → ukuzalisa, i-ejenti yokuthambisa, isasazi → uncedo lokucubungula → i-accelerator
c.Inkqubo yokucoca: inokuxuba ngcono, ngokukhawuleza, nangaphezulu ngokulinganayo
Indlela yemela: a. Indlela yemela etyibilikayo (indlela yeemela ezisibhozo) b. Indlela yokusonga unxantathu c. Indlela yokusebenza yokujija d. Indlela yokuncamathela (indlela yemela yokuhamba)
d.Ifomula yokubala umthamo wokulayisha we-mill evulekile yi-V = 0.0065 * D * L, apho i-V - ivolumu ye-D yi-diameter ye-roller (cm) kunye no-L ubude be-roller (cm)
e.Ubushushu be-roller: i-50-60 degrees
f.Ixesha lokuxuba: Akukho mmiselo othile, kuxhomekeke kubuchule bomqhubi
(2)Umxube wangaphakathi:
a.Inqanaba elinye lokuxuba: Emva kwenqanaba elinye lokuxuba, inkqubo yokuxuba imi ngolu hlobo lulandelayo: irabha ekrwada → imathiriyeli encinci → i-ejenti yokuqinisa → isithambisi → ukukhutshwa kwerabha → ukongeza isulfure kunye ne-accelerator kwi-tablet cinezela → ukothula → ukupholisa nokupakisha
b.Isigaba sesibini sokuxuba: Ukuxuba kwizigaba ezibini. Inqanaba lokuqala yirabha ekrwada → imathiriyeli encinci → into yokomeleza → isithambisi → ukukhupha irabha → ukucofa ithebhulethi → ukupholisa. Inqanaba lesibini yirabha kamama → isulfure kunye neaccelerator → ukucofa ithebhulethi → ukupholisa
(3)Imiba yomgangatho oqhelekileyo kunye nerabha edibeneyo
a.I-agglomeration edibeneyo
Izizathu eziphambili zezi: ukucocwa okungonelanga kwerabha ekrwada; I-roller pitch egqithisileyo; Umthamo wokunamathela ngokugqithisileyo; Ubushushu obugqithileyo be-roller; Ikhompawundi engumgubo iqulethe amaqhekeza arhabaxa okanye amaqoqo;
b.Umxhuzulane ogqithisileyo okanye onganelanga okanye usasazo olungalinganiyo
Isizathu: Umlinganiselo ongachanekanga we-ejenti yokudibanisa, ukuxuba okungalunganga, ukushiywa, ukudibanisa okungalunganga okanye ukushiywa ngexesha lokuxuba.
c.Tshaza iqabaka
Ikakhulu ngenxa yokusetyenziswa ngokugqithiseleyo kwezongezo ezithile, ezidlula ukunyibilika kwazo kwirabha kwiqondo lokushisa. Xa kukho ukugcwaliswa okumhlophe kakhulu, izinto ezimhlophe nazo ziyakutshizwa ngaphandle, okubizwa ngokuba yi-powder spraying
d.Ubunzima buphezulu kakhulu, buphantsi kakhulu, abulingani
Isizathu kukuba ukulinganiswa kwee-agent ze-vulcanizing, i-accelerators, i-softeners, i-reinforcing agents, kunye ne-rubber eluhlaza ayichanekanga, kwaye ibangelwa ukongezwa okungalunganga okanye okuphosiweyo, okubangelwa ukuxuba okungafaniyo kunye nobunzima obungalinganiyo.
e.Ukutshisa: Isenzeko sakwangoko se-vulcanization yemathiriyeli yerabha
Isizathu: Inhlanganisela engafanelekanga yezongezo; Ukusebenza ngokungafanelekanga kokuxuba irabha; Ukupholisa okungafanelekanga kunye nokupaka; Iimpembelelo zemozulu, njl
3.Sulphurization
(1)Ukunqongophala kwezinto
a.Umoya phakathi kwesikhunta kunye nerabha awukwazi ukukhutshwa
b.Ubunzima obunganelanga
c.Uxinzelelo olunganelanga
d.Ulwelo olubi lwemathiriyeli yerabha
e.Ubushushu obugqithisileyo bokungunda kunye nezinto zerabha ezitshisiweyo
f.Ukutshisa kwangoko kwezinto zerabha (izinto ezifileyo)
g.Ubunzima bezinto ezingonelanga kunye nokuhamba okunganelanga
(2)Amaqamza kunye neepores
a.I-vulcanization enganelanga
b.Uxinzelelo olunganelanga
c.Ukungcola okanye amabala e-oyile kwi-mold okanye kwi-rubber material

e.I-ejenti encinci ye-vulcanization yongeziweyo, isantya se-vulcanization sicotha kakhulu
(3)Ulusu olunzima kunye nokuqhekeka
a.Isantya se-vulcanization sikhawuleza kakhulu, kwaye ukuhamba kwerabha akwanele
b.Iimbumba ezimdaka okanye amabala ancamathelayo
c.Ukwahlukaniswa kakhulu okanye i-arhente yokukhulula
d.Ubunzima obunganeleyo bezinto ezincamathelayo
(4)Ukuqhekeka kwemveliso
a.Ubushushu obugqithisileyo bokungunda okanye ukuba sesichengeni sesulfure ixesha elide
b.Ukugqithiswa kwedosi ye-ejenti ye-vulcanizing
c.Indlela yokudiliza ayichanekanga
(5)Kunzima ukuqhubekeka
a.Amandla okukrazula kwemveliso kuhle kakhulu (njengokuncamathelisa okuphezulu). Le nkqubo inzima ibonakala ngokungakwazi ukukrazula i-burrs
b.Amandla emveliso ahlupheke kakhulu, abonakaliswe njengama-brittle edges, anokukrazula imveliso kunye
