Ukwakheka okuhlukahlukene kodaka

Izinhlobo Zodaka Lomquba Omile kanye Namafomula Ayisisekelo

1. Ukuhlukaniswa komkhiqizo

① Ngokomsebenzi wokuplasta udaka, ungahlukaniswa:

Ngokujwayelekile, udaka lokukhonkolo lungahlukaniswa lube udaka olujwayelekile lokuplasta, udaka lokukhonkoloza lokuhlobisa, udaka lokuplasta olungangeni manzi kanye nodaka olunamekiwe olunemisebenzi ethile ekhethekile (njengokuvikela ukushisa, ukumelana ne-asidi, nodaka oluvikela imisebe).

② Ukuhlukaniswa ngokwezinto zikasimende ezisetshenziswa odakeni lokuplasta

A.Ukunamathisela udaka ngezibophezelo ze-inorganic (usimende, i-gypsum noma i-slaked lime).

B.Izisituko ezihlobisayo zisebenzisa usimende, impushana ehlakazeka kabusha noma i-slaked lime njengesibopho.

C.Ama-plaster asekelwe kusimende asetshenziselwa izinto zangaphandle kanye namakamelo amanzi, kanti ama-plaster asekelwe ku-gypsum asetshenziselwa izindonga zangaphakathi kuphela.

2. Ifomula yereferensi

Ngodaka lokunamathisela lwezindonga zangaphakathi nezangaphandle zezindonga zezitini ezingasebenzi ngokukhethekile, ngokuvamile kuvame kakhulu ukukhetha amandla acindezelayo angu-10MPa noma angu-15MPa, kodwa imikhiqizo enamandla aphansi namandla aphezulu ingenziwa futhi ngokuhambisana nokukhethekile okukhethekile. izidingo.

Isiphakamiso sefomula siwukwengeza u-1%~4% RE5010N kusimende noma kusimende osuselwa kusimende, ongathuthukisa ukunamathela kwawo, ukumelana nokugqokwa nokuguquguquka.Ngaphezu kwalokho, kuyanconywa futhi ukwengeza u-0.2%~0.4% we-cellulose ether, isitashi ether noma ingxube yakho kokubili.Kunconywa ikakhulukazi ukusebenzisa i-polymer powder ehlakazeka kabusha i-RI551Z kanye ne-RI554Z ene-hydrophobicity ukuze kuthuthukiswe ukusebenza kokuplasta nokuplasta.

I-Mortar Additive Masterbatch Isingeniso

I-masterbatch ye-mortar additive iqukethe lezi zingxenye ezilandelayo: i-sodium fatty alcohol polyethylene sulfonate, i-cellulose, i-sodium sulfate, i-starch ether, njll.

Imisebenzi eyinhloko: ukuqinisa umoya, ukuqina, ukugcinwa kwepulasitiki, ukuthuthukiswa kokusebenza kanye neminye imiphumela eyingqayizivele, okuwukuphela komkhiqizo ezweni ongahlanganisi ngokuvumelana nenani likasimende.Ukonga usimende odakeni oluxubekile akukwazi nje ukuqinisekisa amandla kodwa futhi kuthuthukise ukuqina, ukungakwazi ukuqina nokumelana nokuqhekeka.

Izici Nezici Zokusebenza Nezici Zokusebenza Nezici Zokusebenza Nokusebenza:

1. Ukuthuthukisa ukusebenza kodaka nokusebenza kahle kwabasebenzi

Ngesikhathi sokwakha nokukhonkoloza, udaka likhulu, luthambile, futhi lunamandla aqinile okuhlangana.Indawo enamathelayo ayinamatheli efosholoni, inciphisa umlotha kanye nezindleko, kanti udaka lunezinga eliphezulu lokugcwala.Inezidingo eziphansi ngezinga lokumanzisa kodonga, futhi ukushwabana kodaka kuncane, okunqoba izinkinga ezivamile njengokuqhekeka, izimbobo, ukuchitheka, nokuphuma amagwebu odongeni, futhi kuxazulule inkinga yokusebenza kodaka.I-mortar igcinwa amahora angu-6-8 ngaphandle kwe-sedimentation, ukugcinwa kwamanzi okuhle, akukho ukuhlukaniswa kodaka ethangini lomlotha, futhi asikho isidingo sokuxubha okuphindaphindiwe, okusheshisa isivinini sokwakha futhi kuthuthukise ukusebenza kahle komsebenzi.

2. Umphumela wamandla wangaphambi kwesikhathi

Udaka oluxubene nezithasiselo zodaka lunobudlelwano kanye nomphumela oqinisayo ngosimende.Ngenqubo yokwenza ipulasitiki, ifinyelela amandla athile ngemuva kwamahora angama-5-6 wokusetshenziswa, futhi amandla akamuva angcono.

3. Ukonga amanzi

Udaka olulungiselelwe ngezithako zodaka lunomphumela wokuhlukanisa emanzini, okunganciphisa ukusetshenziswa kwamanzi, ukunciphisa ukuncipha kwezindonga ezikhonjiwe futhi kuthuthukise amandla.

4. Imisebenzi eyengeziwe

Udaka olulungiswe ngezithasiselo zodaka lunemisebenzi yokugcina amanzi, ukunciphisa umsindo, ukulondoloza ukushisa, ukuvala ukushisa, nokumelana nesithwathwa.

Ukwakhiwa kanye nenqubo yokukhiqiza ye-polyvinyl acetate emulsion adhesive

1. Ifomula

I-vinyl acetate: 710 kg

Amanzi: 636 kg

2. Inqubo yokukhiqiza

Faka utshwala be-polyvinyl namanzi egedeni lokuncibilika, ugovuze imizuzu eyi-10 bese ushisa kuze kufike ku-90 ° C, uhlakaze amahora angu-4, bese uncibilika ube yisixazululo esingu-10%.Ngemva kokuhlunga isixazululo samanzi se-PVA esincibilikisiwe, sibeke ethangini le-polymerization, engeza u-100 kg we-octylphenol polyoxyethylene ether kanye ne-primer monomer (cishe i-1/7 yenani eliphelele le-monomer), kanye ne-persulfuric acid ene-concentration ye-10% 5.5 kg ye-ammonium isixazululo, vala imbobo yokudla, futhi uvule amanzi okupholisa.Qala ukushisa, futhi izokhuphuka ifike ku-65°C phakathi nemizuzu engama-30.Lapho amaconsi awuketshezi evela engilazini yokubona, vala i-valve yesitimu (cishe imizuzu engama-30-40), futhi izinga lokushisa lizokhuphuka libe ngu-75-78°C.umzimba (ukwengeza okuphelele phakathi kwamahora angu-8-9).Ngesikhathi esifanayo, engeza amagremu angu-50 we-ammonium persulfate ngehora (ehlanjululwe izikhathi ezingu-10 zamanzi).Izinga lokushisa lokusabela liphezulu kakhulu noma liphansi, futhi izinga lokugeleza kwe-monomer eyengeziwe kanye nenani lesiqalisi lingalawulwa ngendlela efanele, kodwa inani eliphelele lefomula akumele leqiwe.Rekhoda isimo se-reflux kanye nezinga lokushisa lokusabela lokungezwa kwe-monomer njalo ngemizuzu engama-30, futhi urekhode izinga lokugeleza lokungezwa kwe-monomer kanye nenani lesiqalisi njalo ngehora.

Ngemuva kokungeza i-monomer, bheka izinga lokushisa lesixazululo sokuphendula.Uma iphezulu kakhulu (ngaphezu kuka-85°C), amagremu angu-440 e-ammonium persulfate angengezwa ngokufanelekile.95°C, hlala ufudumele imizuzu engu-30, upholile ube ngaphansi kuka-50°C, engeza isixazululo se-sodium bicarbonate.Ngemuva kokubona ukuthi ukubonakala kwe-emulsion kuyafaneleka, engeza i-dibutyl phthalate, gxuma ihora elingu-1, bese ukhipha.
