Kune mamwe maitiro ekushambadza atinoziva asi vanhu vazhinji vanogona kuramba vari murima. Semuenzaniso,
Muchikafu mune 0 sucrose, asi hazvirevi kuti haina shuga,
Hapana mafuta ari muchikafu, asi haaenzane nemacalorie.
Mamwe maitiro anogona kunzi akaoma kudzivirira akadai sesimbi ye "silicone" sealant. (Chisimbiso che "green" chinoreva chisimbiso chine hushamwari nezvakatipoteredza )
Zvivharo zvesilicone zvave zvichishandiswa mukuvaka kwemakore mazhinji, uye zvinowanzoshandiswa pakusunga nekubatanidza mukuvaka madziro emaketeni, magonhi nemahwindo, magungano nedzimwe nzvimbo. Nekufambira mberi kwekukura kwemaguta, zvivharo zvesilicone zvapinda mumativi ese ehupenyu. , Mwenje, midziyo yemumba nezvimwe zvinhu zvidiki zvinoita basa risingakosheswi. Parizvino, zvivharo zvesilicone zviri kushandiswa zvakanyanya, uye zvinodiwa nevatengi zvezvivharo zvesilicone hazvingogumiri pamabasa ekutanga ekubatanidza nekusimbisa. Panguva imwecheteyo, kushanda kwekabhoni kaviri kwakaisawo zvinodiwa zvitsva zvekuburitsa hutsi hwese muzvivakwa. Pasi pekuisa zvinhu zviviri, zvivharo zvesilicone zvegirini uye zvine hushamwari kune zvakatipoteredza zvava tsika itsva muindasitiri.
Zvinodiwa zvitsva zvakurudzira misika mitsva. Vatengiwo zvavo vanofanira kusarudza sei silicone sealants chaiyo "yakasvibira"?
Nhasi, tinowana mhinduro pamwe chete nemi!
1. Ndezvipi zvinhu zvinofanira kuonekwa se "green" silicone sealant chaiyo?
Tisati tatsanangura zvigadzirwa zve "green" sealant, tinofanira kutanga tanzwisisa kuti chii chinonzi "green" chigadzirwa? Kazhinji zvatinodaidza kuti zvigadzirwa "green" zvinofanira kutongwa kubva pazvinhu zvina zvesimba, zviwanikwa, nharaunda uye mhando ("General Rules for Green Product Evaluation" GB/T33761-2017).
Munyaya yezvivhariso, hunhu huviri hwesimba nezviwanikwa hahuna simba guru pakushanda kwezvivhariso zvesilicone. Nzvimbo nehunhu hwave hunhu huviri hwakakosha pakuongorora kana zvivhariso zvesilicone zviri "zvegirini". VOC yakaderera, chepfu shoma yemuviri, Hunhu hwepamusoro (kwete mafuta akawedzerwa) nezvimwewo zvinowira muchikamu chezvose zviri zviviri.
2. Ungatsanangura sei VOC yakaderera? Ndeipi chiyero chezvino pamusoro pemuganhu weVOC?
Pakati pezvinhu zviviri zvakatipoteredza uye mhando, VOC shoma inogona kunzi ndeimwe yehunhu hwezvakatipoteredza hunozivikanwa zvikuru nevatengi. Kare muna 2001, mitemo iyi yenyika yakajekesa zvinodiwa kuti pave nemiganhu yezvinhu zvinokuvadza muzvivharo zvekushongedza mukati——
GB 18583 "Zvinhu zvekushongedza mukati - Miganhu yezvinhu zvine njodzi muzvinonamira"
GB 30982 "Miganhu Yezvinhu Zvine Ngozi Muzvinonamira Zvekuvaka"
GB/T 33372 "Miganhu yeMakomponi Ezvisikwa Asina Kugadzikana muZvinonamira"
……
Musi wa4 Kurume, 2020, National Standardization Management Committee yakaburitsa standard itsva GB 33372-2020 "Miganhu yeVolatile Organic Compounds muAdhesives", iyo yakagovanisa zvakare zvinodiwa zveadhesives munzvimbo dzakasiyana siyana dzekushandisa. Kune rudzi rumwe chete rweadhesive, miganhu yakasiyana yeVOC content values inosiyaniswawo zvichienderana nemamiriro chaiwo enzvimbo dzakasiyana dzekushandisa.
▼Muganho wehuwandu hweVOC hwezvinonamira zvakawanda (GB 33372-2020)
3. Pamusoro peVOC yakaderera, ungatsanangura sei zvimwe zvinhu uye mashandiro e "green" silicone sealants?
01. Huturu Hwakaderera Mumuviri
Parizvino, mainstream neutral silicone sealants ari pamusika anogona kukamurwa kuita maalcohol type uye ketoxime type sealants zvichienderana nezvinhu zvidiki zvinoburitswa panguva yekurapwa. Alcohol-type sealants, mamorekuru madiki anoburitswa panguva yekurapwa anowanzova mamorekuru madiki ealcohol akadai semethanol, ethanol (inozivikanwa sealcohol), uye ketoxime-type sealants, mamorekuru madiki anoburitswa panguva yekurapwa anowanzova ketone oximes akadai sebutanone oxime.
Kuedzwa kweToxicity yePhysiological (Mienzaniso yeMiti)
Mhando mbiri dzezvinovhara nemiti imwechete dzakaiswa munzvimbo yakavharwa kwemazuva gumi, uye simba remhando dzakasiyana dzezvinovhara pakukura kwemiti imwe chete rakaongororwa. Musiyano mukuchengetedzwa kwezvakatipoteredza pakati pezvinovhara zvemhando yealcohol neketoxime wakaenzaniswa nehutachiona hwebiotoxicity.
Mhedzisiro yekuyedza ndeiyi inotevera:
Mhedzisiro yekuyedza inoratidza kuti mamorekuru madiki edoro anoburitswa panguva yekupisa kwesealant ine alcohol haana mhedzisiro yakaipa pakukura kwezvirimwa, uye ane hushamwari kune nharaunda.
02. Chisimbiso chemhando yepamusoro
Vachinetseka nezvekuchengetedzwa kwezvakatipoteredza uye hutano hwenzvimbo yemukati mezvivakwa,Siwayinokurudzira zvikuru kuti vashandisi vasarudze zvigadzirwa zvemhando yepamusoro uye zvemhando yepamusoro zve sealant, uye vadzivise kutenga nekushandisa zvimwe zvigadzirwa zvemhando yepamusoro uye zvisina kunaka zviri pamusika, zvakaita se sealants dzakazadzwa nemafuta akazadzwa ne chena oil sealant. Haingori chete yakasimba, ichasakara, inotsemuka, uye inobuda, asi mafuta machena akazadzwa mairi acharamba achipararira uye achichinja-chinja, zvichikonzera huwandu hwakawanda hweTVOC, izvo zvinokanganisa nharaunda yemukati, uye mashandiro ekuchengetedza nharaunda haagone kuvimbiswa.
4. Ungasarudza sei rudzi rwe "green" sealant?
Neshoko rimwe chete:
Ingosarudza SIWAY!
Sekambani inotungamira muindasitiri yezvisimbiso, SIWAY yagara yakazvipira kukusimudzira nharaunda yakachengeteka, ine zvakatipoteredza, uye ine hutano. Kune rumwe rutivi, yave ichishandisa pfungwa yekuvandudza zvakatipoteredza mukuita kwese kwekutsvagisa nekugadzira zvigadzirwa, kugadzira fomura, mitemo yekudzora mhando, uye kugadzira zvinhu neunyanzvi.
Kune rumwe rutivi, inopindurawo zvakasimba chikumbiro che "green certification", inotora kuchengetedzwa kwezvakatipoteredza senzira yakakosha yekuvandudza kambani, uye inotungamira indasitiri maererano nemazinga ezvigadzirwa zvegreen. SIWAY yave ichitora chikamu mukuunganidzwa kwemazinga akakodzera akadai se standard yenyika GB/T 35609 "Green Product Waterproof and Sealing Materials" uye standard yeboka T/CECS 10029 "Evaluation of Green Building Materials and Construction Sealants", ichipa mhinduro dzakazara dze adhesive sealing system ine hushamwari kune wese mutengi anotsvaga mhando nerunako.
Une kunzwisisa kwakadzama nezve green silicone sealants here mushure mekuona izvi? Uchiri kuda kuziva chokwadi chechigadzirwa, ndapota tarisira kusangana newe mune ramangwana.
SIWAY inodzivirira mutengi wese ne "Green",
Shingirira, pfuura, uye simbara zvakanaka.
