Udaka lomgubo olomileyo lubhekisa kwigranular okanye kwimathiriyeli engumgubo eyenziwe ngokuxutywa ngokwasemzimbeni kweeaggregates, imathiriyeli yesamente ye-inorganic, kunye nezongezo eziye zomiswa zaze zajongwa ngokomlinganiselo othile.Zeziphi izongezo ezisetyenziswa ngokuqhelekileyo kumgubo wodaka owomileyo?Oku kulandelayo sisingeniso kumxholo ophambili wezongezo zodaka omisiweyo owenziwe nguJianshe Net ukuze ubhekiselele.
Udaka lomgubo olomileyo lusebenzisa isamente yasePortland njengesixhobo sesamente, kwaye isixa semathiriyeli yesamente sidla ngokubalelwa kwi-20% ukuya kwi-40% yodaka olomileyo lomgubo;Uninzi lwee-aggregates ezintle ziyisanti ye-quartz kwaye zifuna isixa esikhulu sonyango lwangaphambili olunjengokomisa kunye nokuhlolwa ukuqinisekisa ukuba ubungakanani bamasuntswana kunye nomgangatho wabo uhlangabezana neemfuno zefomula;Ngamanye amaxesha i-fly ash, i-slag powder, njl.I-Admixtures isetyenziswa ngokubanzi kwiimali ezincinci, ukusuka kwi-1 ukuya kwi-3%, kodwa ibe nefuthe elibalulekileyo.Zihlala zikhethwa ngokweemfuno zefomyula yemveliso yokuphucula ukusebenza, ukubekwa, amandla, ukuncipha, kunye nokumelana neqabaka yodaka.
Zeziphi iindidi ezisetyenziswa ngokuqhelekileyo zezongezo zodaka olomileyo lomgubo?
I-latex powder enokuchithwa kwakhona
EVA copolymerinokuphucula ezi mpawu zilandelayo kudaka lomgubo owomileyo:
① Ukugcinwa kwamanzi kunye nokusebenza kodaka oluxutywe ngokutsha;
② Ukusebenza kokudibanisa kwemigangatho eyahlukeneyo yesiseko;
③ Ukuba bhetyebhetye kunye nokusebenza kokuguqulwa kodaka;
④ Amandla okugoba kunye nomanyano;
⑤ Ukumelana nokunxiba;
⑥ Ukomelela;
⑦ Ukuqina (ukungangeni).
Ukusetyenziswa komgubo welatex onokuphinda uhlakazwe kudongwe olucekethekileyo lokutyatyekwa, isibophelelo sethayile yethayile, inkqubo yokugquma eludongeni yangaphandle, kunye nezixhobo zokuzilinganisa ngokwazo kubonise iziphumo ezilungileyo.
Ukugcina amanzi kunye ne-ejenti yokuqina
Amanzi agcina amanzi atyebileyo aquka i-cellulose ethers, starch ethers, njl njl.ihydroxypropyl methyl cellulose ether(HPMC).
Umsebenzi osisiseko wokunciphisa amanzi kukunciphisa imfuno yamanzi yodaka, ngaloo ndlela iphucula amandla ayo oxinzelelo.Ezona arhente zokunciphisa amanzi ezisetyenziswa kudaka lomgubo owomileyo ziquka i-casein, i-agent yokunciphisa amanzi esekwe kwi-naphthalene, i-melamine formaldehyde condensate, kunye ne-polycarboxylic acid.I-Casein yiPlastiki egqwesileyo esebenza ngokugqwesileyo, ngakumbi kudaka olubhityileyo, kodwa ngenxa yokuba iyimveliso yendalo, umgangatho wayo kunye nexabiso lihlala liguquguquka.I-series ye-Naphthalene yokunciphisa amanzi esetyenziselwa ngokuqhelekileyo i-β-Naphthalenesulfonic acid formaldehyde condensate.
I-Coagulant
Kukho iintlobo ezimbini ze-coagulants: i-accelerator kunye ne-retarder.Ii-accelerators zisetyenziselwa ukukhawulezisa ukusetwa kunye nokuqina kodaka, i-Calcium formate kunye ne-Lithium carbonate zisetyenziswa ngokubanzi, kwaye i-Aluminate kunye ne-Sodium metasilicate nayo ingasetyenziswa njenge-accelerators.Iiretare zisetyenziselwa ukucothisa ukusetwa kunye nokuqina kodaka.I-asidi ye-tartaric, i-citric acid kunye neetyuwa zayo kunye ne-Gluconic acid zisetyenziswe ngempumelelo.
Iarhente yokungangeni manzi
arhente Waterproof ikakhulu ibandakanya: Iron(III) chloride, organic silane ikhompawundi, fatty acid ityuwa, ifayibha polypropylene, Styrene-butadiene kunye nezinye iikhompawundi macromolecular.I-Iron (III) i-agent ye-chloride engenamanzi inesiphumo esihle sokungena manzi, kodwa kulula ukubangela ukugqwala kokuqiniswa kunye neendawo ezifakwe kwintsimbi.Iityuwa ze-calcium ezinganyibilikiyo eziveliswa kukusabela kweetyuwa ze-asidi ezinamafutha kunye ne-calcium ion kwidiphozithi yesigaba sesamente kwiindonga ze-capillaries, zidlala indima ekuthinteleni ii-pores kunye nokwenza ezi ndonga ze-capillary tube zibe yimiphezulu ye-hydrophobic, ngaloo ndlela idlala indima yokungena kwamanzi.Iindleko zeYunithi zezi mveliso ziphantsi, kodwa kuthatha ixesha elide ukuxuba udaka ngokulinganayo namanzi.
Iintsinga ezisetyenziselwa udaka lomgubo owomileyo ziquka ifayibha ye-alkali enganyangekiyo yeglasi, i-polyethylene ifayibha (ifayibha ye-polypropylene), amandla aphezulu kunye ne-modulus ephezulu ye-polyvinyl alcohol fiber (i-polyvinyl alcohol fiber), ifayibha yomthi, njl. iintsinga eziphezulu ze-polyvinyl alcohol kunye ne-polypropylene fibers.Amandla aphezulu kunye ne-modulus ephezulu ye-polyvinyl alcohol fibers inomsebenzi ongcono kunye nexabiso eliphantsi kunemicu ye-polypropylene evela kumazwe angaphandle.Iifayibha zisasazwa ngokungaqhelekanga kwaye ngokulinganayo kwi-matrix yesamente, kwaye zisondelelene ngokusondeleyo nesamente ukuthintela ukubunjwa kunye nophuhliso lwe-microcracks, ukwenza i-matrix yodaka ixinene, kwaye ngaloo ndlela inokusebenza kokungangeni kwamanzi kunye nefuthe elihle kakhulu kunye nokumelana nokuqhekeka.Ubude buyi-3-19 mm.
