Kuhlanganisani ukuhlolwa kwekhwalithi yotshani bokwenziwa?Kunezindinganiso ezimbili ezinkulu zokuhlolwa kwekhwalithi yotshani bokwenziwa, okungukuthi amazinga ekhwalithi yomkhiqizo wotshani bokwenziwa kanye namazinga ekhwalithi yendawo yokugandaya utshani bokwenziwa. Izindinganiso zomkhiqizo zifaka ikhwalithi yotshani bokwenziwa kanye namazinga okuhlola izinto ezibonakalayo zotshani bokwenziwa; amazinga esayithi afaka phakathi ukuba yisicaba kwendawo, ukuthambekela, ukulawula usayizi wendawo kanye nezinye izindinganiso.
Izindinganiso zokuhlola ikhwalithi yomkhiqizo: Izintambo zotshani zokwenziwa zenziwe ngezinto ze-PP noma ze-PE. Izintambo zotshani kumele zihlolwe yizikhungo zokuhlola eziqinile. Abakhiqizi bezintambo zokwenziwa kumele babe nesitifiketi sokuvikela umlilo sezinga lesibili le-SGS, isitifiketi sezinto ezinobuthi neziyingozi, isitifiketi sokulwa nokugqwala, isitifiketi esingagugi, njll.; ngesikhathi esifanayo, utshani. I-glue esetshenziswa phansi nayo ithinta ikhwalithi ye-lurd yokwenziwa, futhi i-glue kumele ibe nesitifiketi sokuvikela imvelo nokuphepha.
Izindinganiso zokuhlola izinto ezibonakalayo zekhwalithi: okungukuthi, ukwelulwa kwefayibha yotshani yokwenziwa, ukuhlolwa kokulwa nokuguga, umbala wetshani yokwenziwa kanye nezinye izindinganiso zokuhlola itshani yokwenziwa. Ukwelulwa kokuthamba kwezintambo zotshani zokwenziwa ohlangothini olude akufanele kube ngaphansi kuka-15% kanye nokwelulwa okuphambene akufanele kube ngaphansi kuka-8%; izinga lamandla okudabuka kwetshani yokwenziwa kumele okungenani libe ngu-30KN/m ohlangothini olude futhi kungabi ngaphansi kuka-25KN/m ohlangothini oluphambene; Izinga lokudabuka kanye namandla okudabuka kwetshani kuhlangabezana nezindinganiso, futhi ikhwalithi yetshani iyathuthukiswa kakhulu.
Izindinganiso zokuhlola umbala: Umbala wotshani udinga ukuhlolwa ukuze kutholakale ukumelana ne-sulfuric acid. Khetha inani elifanele lesampula yotshani yokwenziwa bese uyicwilisa ku-80% sulfuric acid izinsuku ezi-3. Ngemva kwezinsuku ezintathu, qaphela umbala wotshani. Uma kungekho ushintsho embala wotshani, kutholakala ukuthi umbala wotshani wokwenziwa uhlangabezana nezindinganiso zekhwalithi yotshani yokwenziwa.
Ngaphezu kwalokho, utshani bokwenziwa kumele buhlolwe ukuguga. Ngemva kokuhlolwa kokuguga, amandla okuthamba otshani atholakala ukuthi okungenani angama-16 MPa ohlangothini olude futhi angabi ngaphansi kwama-8 MPa ohlangothini oluphambene; amandla okudabuka angabi ngaphansi kwama-25 KN/m ohlangothini olude kanye nama-20 KN/m ohlangothini oluphambene. m. Ngesikhathi esifanayo, ikhwalithi yotshani bokwenziwa nayo idinga ukuba nezindinganiso zokuvimbela umlilo. Ukuze kuvikelwe umlilo, khetha inani elifanele lamasampula otshani bese uwagcwalisa ngesihlabathi esihle esingama-25–80 kg/㎡ ukuze kuvivinywe. Uma ububanzi bendawo evuthayo bungaphakathi kwama-5 cm, buyibanga loku-1, kanti utshani bokwenziwa abukwazi ukusha. Ubulili busezingeni elijwayelekile.
Izinga lokuhlolwa kwekhwalithi yokugandaya indawo ukulawula ukuthamba kwendawo kufike ku-10mm, bese usebenzisa umugqa omncane ongu-3m ukukala ukuze ugweme amaphutha amakhulu; lapho ugandaya utshani, qiniseka ukuthi ukuthamba kwendawo kulawulwa ngaphakathi kwe-1%, bese ukala ngezinga; ukuthamba kulawulwa, Ukuze utshani lukwazi ukumunca amanzi kahle. Ngesikhathi esifanayo, iphutha lobukhulu bobude nobubanzi bensimu yotshani bokwenziwa lilawulwa liye ku-10 mm. Sebenzisa irula ukukala nokugcina iphutha liphansi ngangokunokwenzeka.
Imikhiqizo yotshani bokwenziwa ingahlanganiswa kuphela endaweni egandayiwe ngokuqonda kahle ipharamitha ngayinye.Umkhiqizo wotshani bokwenziwaizinkomba zisebenza kahle kakhulu futhi ziyahlangabezana nezindinganiso. Uma izidingo zokugandaya indawo zingahlangabezani nezindinganiso, utshani bokwenziwa ngeke bukwazi ukukhombisa inani lalo lokusetshenziswa elingcono kakhulu. Ngakho-ke, amazinga ekhwalithi ephezulu otshani bokwenziwa adinga ukuhlanganiswa kwekhwalithi yomkhiqizo kanye nezindinganiso zesayithi, zombili ezibalulekile.
