Polycarboxylate Superplasticizer vs Naphthalene Yakavakirwa: Nhungamiro Inoshanda kubva Munda

Nyaya kubva kuBatching Plant

Rega ndigoverane ndangariro kubva pakutanga kwebasa rangu. Yaiva faundesheni yakakura, pakati pezhizha. Takashandisa naphthalene-based superplasticizer. Rori yakasvika zvayo. Maminitsi gumi gare gare, vashandi vakavhunduka. Kudonha kwakanga kwaenda. “Iri kugadzika sedombo!” Foromani vakapopota. Taifanira kuramba mitoro. Zuva iroro, ganhuriro dzomunhu mukuru teknolojia zvinotidyira nguva nemari. Makore gare gare, ine polycarboxylate superplasticizers (PCEs), Ndakaona kudira maawa ekupedzisira mukupisa kunopisa nekugona kushanda kwakakwana. Musiyano wakanga usiri makemikari chete; zvaikosha. Rega ndikufambise kuburikidza nekuenzanisa kwepasirese pakati peaya maviri ekona admixtures.

Mibvunzo Yako, Akapindura

Kubva pahurukuro dzisingaverengeki nevanjiniya, vatungamiri vepurogiramu, uye kongiri finishers, heino mibvunzo yakajairika pamusoro polycarboxylate superplasticizer vs naphthalene yakavakirwa zvinoderedza mvura.

1. Chii chinonzi musimboti makemikari musiyano?

Naphthalene-based superplasticizers (Iyo inonziwo sulphonated naphthalene formaldehyde condensates, kana SNF) mapolymer akagadzirwa kubva kukemikari cheni ye naphthalene mhete. Chiito chavo chiri kunyanya electrostatic. Vanopfeka zvimedu zvesimende nechaji isina kunaka, zvichiita kuti vadzoserwe mumwe nemumwe. Funga nezvekuisa matanda mamwechete emagineti pamwechete. Kudzingirwa uku kunosunungura mvura, kunatsa kuyerera. Polycarboxylate superplasticizers (PCEs) kuve neyakaomarara “muzinga” chimiro chepolymer. Vanoshandisa nzira mbiri: electrostatic repulsion uye steric chipingamupinyi. Iyo yakareba polymer “miswe” kudzivirira simende zvidimbu kubva pakugwamba. Iyo ine simba rakawanda, yakasimba, uye tunable fomu yekuparadzira.

2. Ndeipi iyo inopa kuchengetedza kurinani kwekudonha?

Polycarboxylate superplasticizers inokunda, maoko pasi. Yavo steric hindrance mechanism yakagadzikana. Haisi kuparara nekukurumidza. Vazhinji vashandisi pamakontrakta maforamu seReddit vanotaura izvi: “Kuchinjira kuPCE yaive shanduko-yemutambo kune yedu refu-haul yakagadzirira-musanganiswa kuburitsa. Isu tinowana kufanofungidzira kushanda kwepamusoro 90 maminitsi, kunyangwe kuchipisa.” Naphthalene-based zvigadzirwa zvinogona kutambura nekudonha nekukurumidza kurasikirwa. Iyo electrostatic repulsion inopera semendi hydrates. Izvi zvinowanzomanikidza vashandi kuti vawedzere zvimwe mvura panzvimbo, kukanganisa simba.

3. Vanoita sei simba rekongiri?

Zvose zvinowedzera simba nekubvumira mvura yakaderera-simende reshiyo. Zvisinei, MaPCE anowanzo kuwana masimba ekupedzisira ekupedzisira ekudonha kwakapihwa. Kupararira kwavo kwepamusoro kunogadzira denser, paste yakawanda ine homogeneous paste ine zvikanganiso zvishoma. Naphthalene-yakavakirwa zvigadzirwa dzimwe nguva zvinogona kukonzera kudiki kwemhepo, izvo zvishoma zvinoderedza simba. Zvemapurojekiti anoda 10,000+ psi kongiri kana kuti kunyanya kusimba, PCE ndiyo yakasarudzwa sarudzo.

4. Pane misiyano yemitengo?

Ehe. Naphthalene-based superplasticizers inowanzo kuchipa parita. Asi mutengo-unoshanda hausi wemutengo weyuniti. MaPCE anoshanda zvakanyanya. Iwe unoshandisa a zvakanyanya kuderera dosage- kazhinji 1/3 ku 1/2 yeinojairwa naphthalene dose-kuwana kuderedzwa kwakafanana kwemvura. Kana iwe uchifunga nezvekuita, marara akaderedzwa, uye kushomeka kwemusoro wepa-site, iyo yakazara mutengo wepurojekiti inowanzofarira maPCE ebasa rakakosha kana rakakura.

5. Ndeipi iri nani kune mamiriro ekunze anopisa kana nguva refu yekudhonza?

Polycarboxylate superplasticizers. Kuchengeta kwavo kwakanakisa kudonha kwakagadzirirwa-kugadzirirwa matambudziko aya. Munzvimbo dzinopisa kana nzvimbo dziri kure nechirimwa, PCEs inopa yakakosha kuchengetedza margin. Naphthalene-based admixtures inogona kuda yakaoma, Kutora nguva nevanodzoreredza, kuwedzera njodzi. Iko kugadzikana kwePCEs inorerutsa zvinhu uye inovandudza kutonga kwemhando.

6. Zvakadini nekuenderana nezvimwe zvinhu?

MaPCE anowanzo kuve nekuenderana kurinani nehupamhi hwesimende uye zvekuwedzera zvinhu senge nhunzi dota kana slag.. Kemikari yavo inowanza kuita zvakawanda. Naphthalene-yakavakirwa zvigadzirwa zvinogona kuva finicky. Vanogona kukonzera kunonoka kwakanyanya kana kukurumidza nemamwe marudzi esimende. Nguva dzose, nguva dzose kuita miedzo yebasa-nzvimbo. Ndakaona mapurojekiti achimira nekuti kutakurwa kutsva simende hakuna kuita zvakanaka neiyo naphthalene formula..

7. Imwezve inogoneka?

Polycarboxylate superplasticizers kazhinji ine mupendero pano. Kubudirira kwavo kwepamusoro kunoderedza huwandu hwemakemikari anodiwa pa cubic yadhi yekongiri. Mamwe maPCE emazuva ano akagadzirwawo ane bio-based kana yakaderera-VOC zvikamu. Iyo indasitiri iri kuenda kwavari kune mapurojekiti ekuvaka egirinhi achitsvaga LEED mapoinzi. Iyi ndiyo nzira yakakosha yemangwana.

8. Ndirini pandinofanira kufunga nezve naphthalene-based?

Usazvinyora. Ivo vakanyatsokodzera kune akawanda akajairwa maapplication. Shandisa naphthalene-based superplasticizers ye: zviri nyore precast zvinhu nekukasira kuiswa, yakaderera kusvika pakati-renji simba kongiri (3,000-5,000 psi), uye mapurojekiti uko mutengo wekutanga ndiwo chaiwo mutyairi wekutanga uye njodzi dzekuita ishoma. Ivo vakapupurirwa, economical workhorse yebasa rakakodzera.

Zano Rangu reProjekti Yako Inotevera

Tanga nezvido zvepurojekiti yako zvisingagone kutaurirana. Kudzivirirwa kwapera 60 maminitsi anokosha? Sarudza polycarboxylate superplasticizer. Iri nyore slab kudira nenguva pfupi yekufambisa? A naphthalene-based product inogona kukwana. Mutemo wangu wegumbo: nokuda kwepamusoro-soro, yakasimba, kana logistically yakaoma kongiri, yemazuva ano PCE tekinoroji ndiyo mhinduro yepamusoro. Inopa kutonga, kuwirirana, uye kazhinji zviri nani kwenguva refu kukosha. Pamberi pekudira kwako kunotevera, usangoodha admixture-iedze. Mhanya mabhechi madiki neyako chaiyo musanganiswa dhizaini. Enzanisa manzwiro, kuderera nekufamba kwenguva, uye kuguma. Iyi maoko-pane nhanho ndiyo nzira yakanakisa yekuona iyo polycarboxylate superplasticizer vs naphthalene yakavakirwa mutsauko iwe pachako uye ita sarudzo ine chivimbo.
